Question

the _______________ of emails from my professor gave me anxiety.
juxtaposition onslaught manipulation clarification

Explanation:

To solve this, we analyze each word's meaning:

• "juxtaposition" means placing side by side, not fitting the context of emails causing anxiety.
• "onslaught" means a fierce or overwhelming attack, which fits the idea of a large number of emails (an overwhelming amount) causing anxiety.
• "manipulation" is about controlling or influencing, not related to the quantity of emails.
• "clarification" is about making something clear, which wouldn't cause anxiety. So "onslaught" is the correct choice.

Answer:

B. onslaught
