Is this sentence compound, complex, or compound complex?

Charity groups distributed food and safe drinking water, and they handed out sleeping bags and mosquito nets, which were needed in the tropical climate.

Is this compound complex?

I do think so.

To determine whether the given sentence is compound, complex, or compound-complex, let's break it down first.

The sentence is: "Charity groups distributed food and safe drinking water, and they handed out sleeping bags and mosquito nets, which were needed in the tropical climate."

This sentence contains two independent clauses, which are:
1. "Charity groups distributed food and safe drinking water."
2. "They handed out sleeping bags and mosquito nets, which were needed in the tropical climate."

Additionally, the second independent clause also includes a dependent clause: "which were needed in the tropical climate."

Based on this analysis, we can conclude that the sentence is compound-complex because it contains two independent clauses and one dependent clause.

So, the answer is compound-complex.
