People often spent their (A)/energy trying to be someone else (B)/or trying to…

Answer: 'Spent' should be 'spend'.

Corrected sentence: People often spend their energy trying to be someone else or trying to live up to someone else's definition of success.

• Tense and form: The sentence describes a habitual action, so the simple present is required. 'Spent' is past tense; use the base verb 'spend' with a plural subject.

• Subject-verb agreement: The subject 'people' is plural, so do not add an -s to the verb; use the base form 'spend'.

• Other words: 'someone' (as part of 'someone else'), 'live' (in 'live up to'), and 'definition' are all used correctly and do not need changes.
