I wonder how he will … being absent from school for a long time.

Analyze the question: We need a phrasal verb with "make" that fits "being absent from school for a long time." The sentence is "I wonder how he will __ being absent from school for a long time."

Explain the concept: Phrasal verbs combine a verb with a particle, and the particle changes the meaning.

• make up for = to compensate for something lost or missed
• make out = to understand, see, or pretend
• make off = to run away (usually with "with")
• make in = not a standard phrasal verb

Step-by-step solution:

1. The sentence is about a student who has missed school and the lost time that must be recovered.
2. The meaning needed is "compensate for" or "catch up on what was lost."
3. "Make up for" fits perfectly: "how he will make up for being absent from school."
4. The other options do not work: • "make in being absent" is not idiomatic. • "make off being absent" is meaningless here. • "make out being absent" would suggest pretending or understanding, which does not fit.

Note on the options: The full idiom is "make up for," and the preposition "for" is missing from the options. Of the choices given, "make up" is the only one that forms the correct phrasal verb. Since "for" follows the gap, the sentence reads naturally as "make up for being absent."

Answer: B. make up

Tip: Remember "make up for" = compensate. Think of "making up for lost time." Whenever an exam sentence talks about absence, a mistake, or a loss that must be corrected, "make up for" is usually the answer.
