The complex sentence is A. After Henry submitted his essay, he realized that he hadn't proofread the last page.
<u>A complex sentence is a sentence that contains an independent clause and a dependent clause</u>. In contrast to an independent clause, a dependent clause cannot stand alone to form a complete sentence. Moreover, dependent clauses are always introduced by a subordinating conjunction. In this sentence,<u> the dependent clause is "After Henry submitted his essay", the subordinating conjunction is "after" and the independent clause, which can stand by itself, is "he realized that he hadn't proofread the last page"</u>.
The main idea of the paragraph is that women should be credited for much more during the prehistoric times that they are at the moment. We only get the picture of them being rather irrelevant at the time which is obviously not true, based on this excerpt. The paragraph is quite feminist, meaning that it is shedding light on actual history and the role of women in such a society which not much is spoken about in contemporary analyses.
They were the ones who invented gardening, as well as pottery and weaving. The reason why they did this was because they often stayed 'at home' taking care of children, so they had time to do other things as well, while men were out hunting and providing for the family in other ways. Thus we have solid proof that women were far more creative and responsible for various things than they are credited for now.
