Grove Decisions and Clues

27 fictional creature questions combining deduction, planning and story constraints. Nine families contain three distinct cases.

Choose a response. See the reasoning.

Read the facts, pick the answer that best fits the stated goal, then open the explanation. Start with five or browse the full set. There is no timer or personal assessment; the useful part is understanding the choice.

These are original web companion exercises. They are independent of the app; answers and progress do not transfer. All people and records in the scenarios are fictional.

01 / reasoning

Two activity windows case 1

Two grove activities must occupy different windows: morning and afternoon. Painting can happen in either window, but Pip can join the reading activity only in afternoon. Both activities must include Pip. Which schedule satisfies every condition?

Show the worked answer

A. Painting morning, reading afternoon

Reading must take afternoon so Pip can join. Because the activities need different windows, painting takes morning. Putting both together ignores the separation rule, while switching them prevents the required participant from joining reading.

Try next: Explain which clue fixes the reading window before placing painting.

02 / reasoning

Two-color festival tokens case 1

A fictional festival basket contains 12 wooden tokens. Exactly one third are painted red, and every remaining token is blue. No other colors occur. How many blue tokens are in the basket once all tokens have been painted?

Show the worked answer

B. 8

One third of 12 is 4, leaving 8 blue tokens. The colors form separate parts of the whole basket, so subtracting the red share is sufficient. The question asks for the remaining color, not the named fraction.

Try next: Draw three equal groups and shade the single red group.

03 / reasoning

Observation or assumption case 1

A story states only that a lantern is on a table and that two creatures walked past earlier. It gives no ownership information or observations of anyone placing it. Which statement is supported directly by the stated evidence?

Show the worked answer

C. The lantern is on the table

The observed location is stated explicitly, while ownership and the action of placing the object are unknown. Walking past does not establish either fact. A supported answer stays within the evidence instead of filling gaps with a story.

Try next: Write a follow-up observation that could establish who placed the object.

04 / judgment

An invitation with a choice case 1

In this fictional dialogue task, the desired invitation must offer participation and explicitly allow declining. A creature wants to invite another to painting. Judge only the wording against those two requirements. Which option meets both stated requirements?

Show the worked answer

A. Would you like to try painting? It is okay to say no.

The selected invitation names an activity and explicitly allows a refusal, satisfying both written requirements. The other options apply pressure or assume a preference. This is a wording exercise, not a guarantee about another person’s feelings.

Try next: Write a different invitation that preserves the same two requirements.

05 / writing

Keep the ending consistent case 1

A fictional story establishes that a creature left its blue hat in the garden and has not returned since. No other character moved it. Which ending follows those facts without adding an unexplained transfer or contradicting the stated location?

Show the worked answer

B. The blue hat is still in the garden.

The item remains in the garden because the story supplies no movement after it was left there. The other endings contradict either the location or the absence of a transfer. A consistent continuation respects established facts.

Try next: Add one explicit event that would make a different ending consistent.

06 / reasoning

Picnic portion check case 1

A fictional picnic expects 5 creatures, each receiving exactly 2 identical treats. There are 12 treats available, and none can be split or shared between portions. After preparing every required portion, what is the surplus or shortage?

Show the worked answer

C. 2 extra

The picnic requires 5×2=10 treats. Comparing this with 12 gives 2 extra. Complete portions must be counted for every creature before deciding whether the supply is sufficient.

Try next: Arrange the treats into equal portions and identify the leftover or missing ones.

07 / reasoning

One shared meeting choice case 1

Three creatures approve different numbered meeting spots. Their lists are 1, 2, 3; 2, 3, 4; and 3, 4, 5. A selected spot must appear on every list, not merely two. Which numbered spot can all three accept?

Show the worked answer

A. 3

Spot 3 appears on all three approval lists. Other displayed spots appear on fewer lists and therefore fail the unanimous-choice rule. Comparing one list with only a second list would leave the third creature’s condition unchecked.

Try next: Cross-check the selected spot independently against every list.

08 / reasoning

Mirror the grove map case 1

A three-by-three grove map has rows A B C, then D E F, then G H I. Reflect the map left-to-right without changing rows. A creature starts in cell A. Which cell is its reflected partner?

Show the worked answer

B. C

Cell A reflects to C. A horizontal reflection exchanges the first and third columns while leaving the middle column fixed, and it never changes row. Rotating the map would produce a different movement rule.

Try next: Pair every cell with its left-to-right reflection.

09 / reasoning

Eliminate the impossible finder case 1

Exactly one of Pip, Moss and Fern found a fictional lost button. Moss did not find it, and Fern did not find it. No fourth creature is involved. Who must have found the button under these complete clues?

Show the worked answer

C. Pip

The two negative clues exclude Moss and Fern, leaving Pip as the only candidate. The conclusion depends on the complete three-creature list and the statement that exactly one found it; without those assumptions, other possibilities would remain.

Try next: State which clue would be needed if a fourth creature were added.

10 / reasoning

Two activity windows case 2

Reading and painting must use different windows, dawn and noon. Reading is available in either window, but painting is available only at noon. Each activity needs one complete window. Which complete schedule meets the availability and separation requirements?

Show the worked answer

A. Reading dawn, painting noon

Painting must occupy noon because that is its only available window. Reading therefore takes dawn to preserve different windows. Place the more constrained activity first, then use the remaining available window for the flexible activity.

Try next: Swap which activity has the restricted availability and solve again.

11 / reasoning

Two-color festival tokens case 2

A fictional festival basket contains 18 wooden tokens. Exactly one third are painted red, and every remaining token is blue. No other colors occur. How many blue tokens are in the basket once all tokens have been painted?

Show the worked answer

B. 12

One third of 18 is 6, leaving 12 blue tokens. The colors form separate parts of the whole basket, so subtracting the red share is sufficient. The question asks for the remaining color, not the named fraction.

Try next: Draw three equal groups and shade the single red group.

12 / reasoning

Observation or assumption case 2

A narrator explicitly watches Moss place a ribbon on a bench. The story gives no information about who owns the ribbon or why Moss placed it there. Which statement is supported directly by the observation rather than an invented motive or ownership claim?

Show the worked answer

A. Moss placed the ribbon on the bench

The witnessed action establishes who placed the ribbon and where. It does not establish ownership or intention. Someone can move an object without owning it, and the same action can arise from more than one motive.

Try next: Write a separate observation that could clarify ownership without guessing.

13 / judgment

An invitation with a choice case 2

A fictional invitation must name a singing activity and offer a different activity if the recipient declines. Simply saying no is allowed, but an alternative must also be stated. Which wording satisfies both the named-activity and offered-alternative requirements?

Show the worked answer

A. Would you like to sing, or would you prefer drawing?

The selected wording names singing and explicitly offers drawing as another choice. The refusal-only option permits declining but lacks the required alternative. Evaluate the two written requirements separately instead of assuming any polite wording meets both.

Try next: Write another invitation that offers a different specific alternative.

14 / writing

Keep the ending consistent case 2

A creature leaves a small bell in the library. Later, the story explicitly says Moss moves that bell into the workshop and nobody moves it again. Which ending respects the complete sequence, including the later movement?

Show the worked answer

A. The bell is in the workshop.

The later stated transfer updates the bell’s location from library to workshop. The earlier location no longer describes its current position. A consistent ending uses the full event sequence rather than stopping at the first established fact.

Try next: Identify the sentence that changes the object’s location.

15 / reasoning

Picnic portion check case 2

A fictional picnic expects 7 creatures, each receiving exactly 3 identical treats. There are 18 treats available, and none can be split or shared between portions. After preparing every required portion, what is the surplus or shortage?

Show the worked answer

C. 3 short

The picnic requires 7×3=21 treats. Comparing this with 18 gives a shortage of 3. Complete portions must be counted for every creature before deciding whether the supply is sufficient.

Try next: Arrange the treats into equal portions and identify the leftover or missing ones.

16 / reasoning

One shared meeting choice case 2

Three creatures approve different numbered meeting spots. Their lists are 2, 4, 6; 1, 4, 7; and 4, 5, 8. A selected spot must appear on every list, not merely two. Which numbered spot can all three accept?

Show the worked answer

A. 4

Spot 4 appears on all three approval lists. Other displayed spots appear on fewer lists and therefore fail the unanimous-choice rule. Comparing one list with only a second list would leave the third creature’s condition unchecked.

Try next: Cross-check the selected spot independently against every list.

17 / reasoning

Mirror the grove map case 2

A three-by-three grove map has rows A B C, then D E F, then G H I. Reflect the map left-to-right without changing rows. A creature starts in cell B. Which cell is its reflected partner?

Show the worked answer

A. B

Cell B reflects to B. A horizontal reflection exchanges the first and third columns while leaving the middle column fixed, and it never changes row. Rotating the map would produce a different movement rule.

Try next: Pair every cell with its left-to-right reflection.

18 / reasoning

Eliminate the impossible finder case 2

Exactly two of Pip, Moss and Fern jointly found a fictional lost button. Pip did not participate, and no fourth creature exists in this story. Which pair must have found it together under these complete participation rules?

Show the worked answer

A. Moss and Fern

Pip is excluded, leaving Moss and Fern as the only two candidates. Since exactly two creatures participated, both remaining candidates must be included. The participation count matters: it determines a pair rather than one individual finder.

Try next: Change the required finder count to one and explain the resulting uncertainty.

19 / reasoning

Two activity windows case 3

Reading and painting need different windows, daytime and evening. Both activities are available only in the evening, and each requires one whole window. Splitting or combining windows is forbidden. Which schedule can satisfy all the stated requirements?

Show the worked answer

C. No valid schedule

Both activities demand the same only available window, while the rules forbid sharing it. Neither can move to daytime. The constraints conflict, so no schedule works without changing at least one availability or separation requirement.

Try next: Name one specific rule change that would make a schedule possible.

20 / reasoning

Two-color festival tokens case 3

A fictional festival basket contains 24 wooden tokens. Exactly one third are painted red, and every remaining token is blue. No other colors occur. How many blue tokens are in the basket once all tokens have been painted?

Show the worked answer

B. 16

One third of 24 is 8, leaving 16 blue tokens. The colors form separate parts of the whole basket, so subtracting the red share is sufficient. The question asks for the remaining color, not the named fraction.

Try next: Draw three equal groups and shade the single red group.

21 / reasoning

Observation or assumption case 3

The story says a map was on a shelf in the morning and was absent in the afternoon. No movement was observed, and no culprit or destination is stated. Which claim is justified by those two observations alone?

Show the worked answer

A. The map was absent in the afternoon

The observations establish a change in the map’s presence on the shelf. They do not identify who moved it, where it went, or whether any wrongdoing occurred. The supported claim stays within the explicitly observed afternoon condition.

Try next: List two different explanations consistent with the same observations.

22 / judgment

An invitation with a choice case 3

A creature has already declined dancing. In this fictional dialogue task, the response must acknowledge that refusal and avoid another request to dance. Which response respects both requirements, judged only by its explicit wording rather than an assumed emotional reaction?

Show the worked answer

A. Okay, no dancing. Another activity can wait.

The selected response accepts the refusal and makes no renewed dance request. The other responses continue pressing for the declined activity. This checks a concrete dialogue constraint without claiming to know what any participant will feel.

Try next: Write a second response that accepts the same refusal without pressure.

23 / writing

Keep the ending consistent case 3

Two identical green bags exist. Bag A stays in the workshop throughout the story, while Bag B is carried home. The ending concerns Bag A specifically, not whichever bag looks similar. Which ending follows the labeled-object facts?

Show the worked answer

A. Bag A remains in the workshop.

Bag A never moves, so its location remains the workshop. Bag B’s movement does not change Bag A’s position even though the bags look alike. Tracking object identity separately from appearance prevents mixing their histories.

Try next: Write a separate location timeline for each labeled bag.

24 / reasoning

Picnic portion check case 3

A fictional picnic expects 8 creatures, each receiving exactly 4 identical treats. There are 35 treats available, and none can be split or shared between portions. After preparing every required portion, what is the surplus or shortage?

Show the worked answer

C. 3 extra

The picnic requires 8×4=32 treats. Comparing this with 35 gives 3 extra. Complete portions must be counted for every creature before deciding whether the supply is sufficient.

Try next: Arrange the treats into equal portions and identify the leftover or missing ones.

25 / reasoning

One shared meeting choice case 3

Three creatures approve different numbered meeting spots. Their lists are 3, 6, 9; 6, 8, 10; and 2, 6, 7. A selected spot must appear on every list, not merely two. Which numbered spot can all three accept?

Show the worked answer

A. 6

Spot 6 appears on all three approval lists. Other displayed spots appear on fewer lists and therefore fail the unanimous-choice rule. Comparing one list with only a second list would leave the third creature’s condition unchecked.

Try next: Cross-check the selected spot independently against every list.

26 / reasoning

Mirror the grove map case 3

A three-by-three grove map has rows A B C, then D E F, then G H I. Reflect the map left-to-right without changing rows. A creature starts in cell D. Which cell is its reflected partner?

Show the worked answer

B. F

Cell D reflects to F. A horizontal reflection exchanges the first and third columns while leaving the middle column fixed, and it never changes row. Rotating the map would produce a different movement rule.

Try next: Pair every cell with its left-to-right reflection.

27 / reasoning

Eliminate the impossible finder case 3

Exactly one of Pip, Moss and Fern found a fictional lost button. The only additional clue says Pip did not find it. Nothing distinguishes Moss from Fern, and no other observation is available. Which conclusion follows from these incomplete clues?

Show the worked answer

C. Either Moss or Fern could be the finder

Pip is ruled out, but both Moss and Fern remain consistent with the one-finder condition. The clues do not select between them. Reporting the two possibilities preserves the distinction between narrowing candidates and identifying a unique answer.

Try next: Add one independent clue that would resolve the remaining uncertainty.
