Are head lice considered a type of parasite?

1. No

2. Yes

3. Only in certain countries

4. Only in animals

The correct answer is: Yes

Head lice are considered a type of parasite because they live on the human scalp and feed on blood from the scalp. They are not found on any animals other than humans, ruling out option D as incorrect. While it is true that head lice are more common in certain countries, this does not change the fact that they are still considered a type of parasite wherever they are found. Therefore, option C is also incorrect. It is important to note that head lice are indeed considered parasites and not simply harmless insects, making option A incorrect as well.
