Break Down the Problem

1. Identify the grammatical structure of the sentence.
2. Determine the correct verb tense needed to fit the context.

Relevant Concepts

• Tenses: Understanding when to use past, present, or future tenses.
• Past Simple vs Past Perfect: Knowing the difference between completed actions and actions completed before another action.

Analysis and Detail

1. The phrase "When we ___ the meeting" indicates a specific time in the past when something occurred. Therefore, we need a past tense form.
2. The options given are:
   • a) will finish (future tense)
   • b) has finished (present perfect tense)
   • c) finished (simple past tense)
   • d) had finished (past perfect tense)

In this context, "when we finished the meeting" works best since it smoothly connects to "we went to eat at the cafe," and indicates that both actions occurred in the past.

Verify and Summarize

Comparing the choices:

• (a) is incorrect because it implies a future action.
• (b) is incorrect as it describes an action that completed relative to the present.
• (c) correctly places both actions in the past.
• (d) is also correct but implies that finishing the meeting occurred before another past action, which isn't necessary here.

Final Answer

The best choice is c) finished.
