To determine which bar on a comparative bar chart will be the tallest, we need to evaluate the given data to identify the highest count. We start by examining the numbers representing both passed and failed subjects for cats and dogs.
The data is as follows:
- Cats who passed: 24
- Cats who failed: 26
- Dogs who passed: 30
- Dogs who failed: 28
Let's compare these numbers:
1. Cats who passed: 24
2. Cats who failed: 26
3. Dogs who passed: 30
4. Dogs who failed: 28
To find the tallest bar, we need to identify the highest number among these options:
- The number for "Cats who passed" is 24.
- The number for "Cats who failed" is 26.
- The number for "Dogs who passed" is 30.
- The number for "Dogs who failed" is 28.
By comparing these values, it is clear that the highest count is 30, which corresponds to "Dogs who passed."
Thus, the bar representing "Dogs who passed" will be the tallest.
Answer: D. Dogs who passed
