---

Passage Summary:



- Mrs. Baker baked chocolate chip cookies and placed them on the kitchen counter to cool.
- She warned her three children — Ben, Emily, and Sam — not to eat any cookies until after dinner.
- She went to the garden to pick vegetables.
- When she returned, the plate of cookies was empty.
- The children were in the living room, with crumbs around their mouths.
- Each child gave an alibi:
- Ben: He was reading a book.
- Emily: She was playing with her dolls.
- Sam: He was drawing a picture.

Key Clue:


> *"The children were playing in the living room, crumbs around their mouths."*

This is crucial. Even though they claimed to be doing different activities, they all had crumbs around their mouths, which suggests that all three had eaten the cookies.

But the question asks: Who do you think ate the cookies?

Let’s examine each child’s alibi:

1. Ben – Said he was reading a book.
→ Reading a book doesn’t require hands or mouth movement. But if he had crumbs around his mouth, it’s possible he ate while reading — but not impossible.

2. Emily – Said she was playing with her dolls.
→ Playing with dolls usually involves hands and might involve talking, but again, could be done while sneaking cookies.

3. Sam – Said he was drawing a picture.
→ Drawing requires holding a pencil and using hands. If he was drawing, he likely couldn't have been eating at the same time — especially not without getting crumbs on the paper or smudging it.

Wait — here's the key detail:

👉 Crums around their mouths — but no mention of mess on their drawings or books or dolls.

But more importantly: Sam was drawing a picture. That means he would have been using his hands and focusing on paper. Eating cookies while drawing would be messy and hard to do discreetly.

However, all three had crumbs, so they must have eaten.

But let’s look deeper.

Critical Observation:


Mrs. Baker said:
> "No cookies until after dinner!"

And she left the cookies on the counter.

The children were in the living room, not the kitchen.

So how did they get the cookies?

They had to go to the kitchen, grab them, and return.

But — crumbs around their mouths = they ate them after taking them.

Now, consider this:

If Sam was drawing a picture, he would need both hands free. Holding a pencil and drawing makes it difficult to eat without dropping crumbs on the paper.

Also, drawing is a focused activity — not something you do while eating.

But Ben and Emily didn’t have such constraints.

Still, all three had crumbs.

So perhaps all three ate the cookies.

But the mystery is: Who ate them?

Let’s re-read what Ben says:
> "I was too busy reading a book."

That implies he was occupied — but reading doesn’t prevent eating.

Emily: playing with dolls — also possible to eat while doing.

Sam: drawing — this is the most suspicious because drawing is harder to do while eating.

But wait — there's another clue.

The plate was empty — meaning someone (or some people) took the cookies from the kitchen.

But none of them were seen going to the kitchen.

And yet, they all had crumbs.

So all three must have gone to the kitchen at some point.

But only one could have been telling the truth.

Wait — let’s consider Sam’s alibi again.

He said he was drawing a picture.

But if he was drawing, and had crumbs around his mouth, that’s okay — maybe he paused.

But here’s the real clue:

> "The children shrugged their shoulders."

They didn’t admit anything.

But then the narrator says: "The mystery was on."

So we are meant to deduce who did it.

Let’s think about who could have eaten the cookies without being noticed.

But here's a better idea:

🔍 The Real Clue: "Crumbs around their mouths"



All three had crumbs — so all three ate cookies.

But the question is: Who ate the cookies?

It could be all of them.

But let’s see if we can find a contradiction.

Wait — Sam said he was drawing a picture.

Drawing a picture takes time and focus.

But if he was drawing, why would he stop to eat?

But Ben and Emily could easily eat while reading or playing.

But here’s the twist:

> "The children were playing in the living room, crumbs around their mouths."

They were in the living room, so they must have gone to the kitchen to get the cookies.

But only one person could have gone — unless they all went together.

But none of them admitted it.

But the key is: Sam was drawing a picture.

What if he was drawing a picture of the cookies?

Or — what if he drew the cookies as part of his drawing?

But no — the passage doesn’t say that.

Wait — the most logical answer is that Sam is lying.

Why?

Because drawing a picture requires concentration and clean hands.

Eating cookies while drawing would leave crumbs on the paper, or smudged lines, or dropped crumbs.

But the story doesn’t mention any mess on the drawing.

Moreover, if Sam was drawing, and had crumbs around his mouth, it’s possible — but less plausible than the others.

But here’s a better idea:

🕵️‍♂️ The Real Answer:



Ben said he was reading a book.

But reading a book — especially a book — can be done while sitting quietly.

But Emily said she was playing with her dolls — also quiet.

But Sam said he was drawing a picture.

Now, drawing a picture — especially for a child — often involves using both hands, and focusing on paper.

But here’s the thing: you can’t eat cookies while drawing without making a mess.

So Sam’s alibi is the weakest.

But wait — the real clue is in the title: *The Mystery of the Missing Cookies*.

And the children all had crumbs.

So all three ate the cookies.

But the question is: Who do you think ate the cookies?

Answer: All three children ate the cookies.

But maybe the puzzle is to figure out who is lying.

But the problem doesn’t ask who lied — it asks who ate the cookies.

Since all three had crumbs, all three ate them.

But let’s consider: Could one of them have eaten all the cookies?

Unlikely — because they were all in the living room, and all had crumbs.

So each one ate at least one cookie.

Therefore, all three ate the cookies.

Final Answer:



Ben, Emily, and Sam all ate the cookies.

Even though they gave alibis, the fact that all three had crumbs around their mouths proves that each of them ate at least one cookie.

So the mystery is solved: The cookies were eaten by all three children.

---

🎯 Explanation:



- The key evidence is crumbs around their mouths — this shows they all ate.
- Their alibis may be true to some extent (they were doing those things), but not exclusively — they could have taken breaks to eat.
- Since the cookies were gone and the kids were in the living room with crumbs, they must have gone to the kitchen earlier.
- No one is completely innocent based on the clues.

---

💡 Conclusion:



> All three children — Ben, Emily, and Sam — ate the cookies.
> They all had crumbs around their mouths, so they all participated in the cookie-eating mystery!

Answer:
👉 Ben, Emily, and Sam all ate the cookies.
