temperature (°c)
8am 10am 12pm 2pm 4pm
when did the temperature first reach 23°c?
○ 10am ○ 11am ○ 12pm ○ 3pm

Explanation:

The graph shows temperature rising from 8am to around 1pm. At 10am, temperature is ~15°C; by 11am (between 10am and 12pm), it reaches 23°C before stabilizing near 12pm. So the first time 23°C is reached is 11am.

Answer:

11am
