Complete: She _____ the prize yesterday.

**The reasoning** This is about **simple past tense** — used for actions that happened and finished at a specific time in the past. The word "yesterday" is your big clue: it tells you the action is completely done. The verb "win" changes like this: - Present: win/wins - Past: **won** - Present participle: winning Since the action happened "yesterday" (past time), you need the past tense form = **won**. **Why the wrong options tempt you** **A) win** — This is present tense (I/you/we/they win). Doesn't match "yesterday." **C) wins** — This is present tense for he/she/it. Sounds familiar because "she" uses it NOW ("she wins every time"), but not for yesterday. **D) winning** — This needs a helping verb like "was" (She was winning). Alone, it's incomplete and doesn't show past time clearly. **Quick takeaway** When you see time words like "yesterday," "last week," "ago" — reach for simple past tense (won, went, ate, did). No helpers, no "-ing."
