Explanation:

Question 1

The passage is about volcanoes. The prefix "volcano - " in "volcanologist" should relate to volcano - related concepts. Volcanoes erupt (fire - like or eruption - related activity). Air pressure (A) is not related, water movement (C) and ice formation (D) are irrelevant. So the prefix refers to fire or eruption.

The word "volcanologist" is a person who studies volcanoes. The suffix "-logist" generally means a person who studies (e.g., biologist - studies biology). A place that creates (B), type of eruption (C), dangerous event (D) don't fit the meaning of "-logist".

The passage says volcanoes are both destructive (destroying things) and creative (lava forms new land). So they can destroy and create land. Option A (only harm) is wrong, option C (rare events) is not stated, option D (no benefits) is wrong as they create new land.

Answer:

B. Fire or eruption
