Question

which best describes what the illustrations in the passage help the reader understand?

1. how to tell male mosquitoes from female mosquitoes
2. where the proboscis and abdomen are located on the mosquito
3. what kinds of sugar male and female mosquitoes need to survive
4. how the female mosquito uses her proboscis to get blood

Explanation:

To determine the correct answer, we analyze each option:

1. Option 1: Illustrations about telling male and female mosquitoes apart would likely show differences in anatomy or behavior specific to sex, but the question is about what the illustrations help understand. This is less likely if the illustrations focus on parts like proboscis and abdomen or feeding.
2. Option 2: If the illustrations are showing the location of proboscis and abdomen, they would be labeled diagrams of the mosquito's body parts. But the other options relate to function or survival.
3. Option 3: Illustrations about sugar types for survival would likely show food sources or chemical structures, not mosquito anatomy or feeding mechanisms.
4. Option 4: Illustrations showing how a female mosquito uses her proboscis to get blood would depict the feeding process, which is a functional illustration. This is more likely as it shows an action (using proboscis) related to the mosquito's behavior, which illustrations can clarify.

Answer:

1. how the female mosquito uses her proboscis to get blood
