B Correct answer
Explanation

8 crows take 8 minutes for 8 buttons, so 1 crow needs 8 minutes for 1 button (rate = 1/8 button per crow-minute). For 16 crows in 16 minutes: 16 × 16 × (1/8) = 32 buttons. The key insight is that output scales with both number of workers and time.

AI explanation

To solve this question, we can use the concept of ratios and proportions.

Let's analyze the given information:

  • 8 crows can steal 8 buttons in 8 minutes.

From this, we can infer that each crow can steal 1 button in 8 minutes.

Now, let's use this information to find out how many buttons can 16 crows steal in 16 minutes.

Since each crow can steal 1 button in 8 minutes, in 16 minutes, each crow can steal 2 buttons (as the time has doubled).

Therefore, 16 crows can steal 2 buttons each in 16 minutes.

So, the total number of buttons that 16 crows can steal in 16 minutes is:

16 crows * 2 buttons/crow = 32 buttons

Therefore, the correct answer is option B) 32.
