Question

First, restating the problem: the sentence to complete is 'They ___________________ (has/have + keep) the intense secret since last week.'

Option analysis:
- The intended structure is the present perfect, which requires the plural subject 'they' to be paired with 'have' as the auxiliary verb, not 'has'. Using 'has' would be correct only with a singular subject (e.g., 'he has kept'). So 'has' is incorrect here because of the plural subject 'they'.

- The base verb given in parentheses is 'keep'. In forming the present perfect, we do not use the bare base form after the auxiliary; we need the past participle. For 'keep', the past participle is 'kept'. Therefore the correct sequence is 'have kept'.

- If someone were to use 'have keep' without converting to the past participle, the sentence would be ungrammatical because the present perfect requires a past participle (have kept), not the bare infinitive (have keep).

- The time phrase 'since last week' indicates a continuing state up to now, which aligns with the present perfect usage. Using a simple present tense (keep) would be odd with 'since' and not reflect ongoing relevance, while using 'have keep' would still be grammatically incorrect due to the incorrect participle form.

Putting it together, the correct completion is: 'They have kept the intense secret since last week.' The combination 'have + kept' satisfies both subject-verb agreement and proper past participle usage for the present perfect tense.
