✅ Why
B is correct:
The passage makes a
comparative claim—that the mosquito is the
“most dangerous” animal in Africa—based on
how many people it kills or harms, especially through the spread of malaria.
To evaluate the
validity of that claim, we need to know:
What do we mean by "most dangerous"? Is it based on:
- Number of human deaths?
- Number of attacks?
- Probability of dying if attacked?
- Economic or social impact?
Understanding the
criteria helps us assess whether mosquitoes meet the standard
better than other animals like the black mamba or hippopotamus.
❌ Why the other options are wrong:
A. Could a person survive an attack by a black mamba if that person received prompt medical attention?- This is too narrow. The passage already says untreated bites are lethal.
- Survival with treatment doesn’t help evaluate whether mosquitoes are more dangerous overall than mambas.
C. Could the incidence of mosquito bites be decreased through the judicious use of pesticides and insect repellent?- This is a solution-focused question. It talks about prevention, not about evaluating the current danger level.
D. Does malaria kill more people per year in Africa than tuberculosis?- This compares two diseases, not animals. The question is about which animal is most dangerous.
E. How does the percentage of people who survive hippopotamus attacks in Africa each year compare with the percentage of people who survive mosquito bites?- Almost everyone survives a mosquito bite (except the unlucky ones who get malaria).
- Comparing survival rates doesn’t help us evaluate total danger or death numbers, which is what the claim is based on.
