Answer:
False. The conclusion does not follow.
Explanation:
The conclusion, that neither the temperature nor the moisture conditions in Malabo are favorable for growing a celery crop, does not follow.
The passage suggests that celery requires a cool weather and a good deal of moisture.
It also states that the weather in Malabo is hot and damp/moist.
Therefore the right conclusion is that, the the moisture condition in Malabo is favorable for growing a celery crop but the temperature is not.
