Answer:
The answer should be B. Respond
Explanation:
The fermenter is sealed off from the air except for a long narrow vent pipe, which allows carbon dioxide to escape from the fermenter. Since there is a constant flow of CO2 through the pipe, outside air is prevented from entering the fermenter, which reduces the threat of contamination by stray yeasts.

A.The powder is an unnatural substance
The answer to the first one would be C. Onomatopoeia. Just for future reference, the definition of Onomatopoeia is the process of creating a word that imitates, resembles, or suggests the sound that it is describing. Here, the bridge made a 'boom' sound, so it is imitating/telling us the sound the bridge made.
The answer to the second one would be B. Hyperbole. He/she most likely doesn't literally have a million things to do, it's just an exaggeration, which is literally what a hyperbole is :)
