What is the reason Alla got a cold, according to the text?

Analysis:

The text presents question C: "C. Yesterday Alla got a cold because ...". The options are:

1. she didn't have an umbrella.
2. she couldn't use her umbrella.
3. it wasn't warm.
4. it wasn't cool

The text states: "But yesterday when I was coming back from school, it started to rain heavily but my umbrella was broken by the strong wind, so I was caught in the rain. I got a cold...".

This directly implies that she got caught in the rain because her umbrella was broken. While option 1 suggests she didn't have an umbrella, the text states she *did* have one, but it was broken. Option 2, "she couldn't use her umbrella," accurately reflects the situation described (broken umbrella meant she couldn't use it effectively).
