Question

Entomology is the science that studies

• A. Behavior of human beings
• B. Insects
• C. The origin and history of technical and scientific terms
• D. The formation of rocks

Hint:

Entomology is the branch of zoology that focuses on the study of insects, which make up a large portion of the animal kingdom.

Answer 1

The Correct Option is B

"Entomology" is often confused with the similarly spelled "etymology," but the two words come from different Greek roots.
"Entomon" means "insect," while "etymon" means "true meaning" (word origin), so entomology and etymology describe completely different fields of study.
Since this question asks specifically about "entomology," it refers to the study of insects, not word origins, human behavior, or rocks.
Therefore, the correct answer is Insects.

Answer 2

Another way to confirm this is by process of elimination, matching each option to the branch of science it actually belongs to.

1. Behavior of human beings: This belongs to psychology, ruling it out as the meaning of entomology.
2. Insects: This is the definition of entomology itself, a branch of zoology focused specifically on insect life.
3. The origin and history of technical and scientific terms: This belongs to etymology, a different field despite the similar-sounding name.
4. The formation of rocks: This belongs to geology, an entirely unrelated earth science.

Eliminating the three unrelated fields leaves insects as the subject of entomology.

Therefore, the correct answer is Insects.
