The eruption of volcano

Explanation:

The volcano named Mount Vesuvius was one of the most dangerous volcanoes in the world and it was a stratovolcano which is characterized by the presence of steep slopes, and alternating layers of volcanic ashes and pyroclastic materials.

The city of Pompeii was located near to this volcano and was destructed when it violently erupted in 78 CE. A large number of pyroclastic materials, along with volcanic ashes, volcanic blocks and toxic gases were released from this volcano at the time of eruption, which covered the city making it up to 6 meters of thick ash beds killing numerous people.

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
