After each of the following sentences, a list of possible interpretations is given. Choose the interpretation…

Analyze the question: The sentence uses the phrasal verb "pull through" and asks what "we did not believe he would" do.

Explain the concept: "Pull through" means to survive a serious illness, injury, or difficult situation, in other words to recover. It is an idiomatic phrasal verb, so you cannot work it out from the separate words "pull" and "through".

Step-by-step solution:

1. The sentence says: "We never believed that Father would pull through that fever."
2. Replace "pull through" with its meaning: "We never believed that Father would recover from that fever."
3. Check each option: • A. recover from the sickness: matches the meaning of "pull through" exactly. • B. acquire immunity to the fever: this is about becoming resistant to a disease, which is a different idea. • C. die from the sickness: this is the opposite. The family did not believe he would survive, but the sentence does not say they believed he would die. Be careful with the double negative: "never believed he would pull through" means they doubted his survival. The phrase itself still means "recover". • D. suffer for so long: the sentence says nothing about the duration of suffering.

Answer: The correct option is A. recover from the sickness.

Exam tip: In idiom and phrasal verb questions, first replace the phrase with your own simple meaning, then match it to the options. Also watch for negatives like "never believed". They make the opposite option (C here) tempting, but the question asks what the phrase means, not what the speakers feared.
