Rice and celery must have a good deal of moisture in order to grow well, but rye and cotton grow best where it is relatively dry. Rice and cotton grow where it is hot, and celery and rye where it is cool. In Malabo, it is very hot and damp. Therefore neither the temperature nor the moisture conditions in Malabo are favorable for growing a celery crop.

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.
