Analyzing the Options

• Option 1: He ate more than he could digest. This is a literal interpretation of the words, not the idiomatic meaning. The idiom is figurative, not about literal eating.
• Option 2: He took up more work than he could handle. This option correctly captures the essence of the idiom. It means undertaking a commitment or task that exceeds one's capabilities or resources.
• Option 3: He tried to explain what he did not understand. This describes confusion or a communication issue, which is different from the meaning of the idiom.
• Option 4: He did not know how much he could endure. While related to capacity, this option focuses on endurance and lack of self-awareness, whereas the idiom specifically refers to taking on *too much* responsibility or work.

Therefore, the most accurate meaning of the sentence is provided by Option 2.
