The temparature of boiling water cannot be measured by temparature

It cannot be measured using clinical thermometer.

Explanation:

Thermometer is an instrument use for measuring temperature that is the degree of hotness and coldness

The temperature of boiling water cannot be measured by clinical temperature or thermometer because it can only measure temperature ranges from 30 to 40°c and the temperature for boiling water is 100°c.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
