Descartes declares "I think therefore I am" as proof of his existence. Explain in your own words what his reasoning is.
Answer: various. Descartes argues that since he knows for sure that he is a thing that thinks, that he must exist. Even if his body or the world around him isn't real, or if his mind is tricked somehow, the fact that he can be tricked at all means that he must exist. In order to be tricked, one has to exist in the first place.

Complete the following sentence by choosing the correct form of the verb in brackets. "Gloria [ran / was running] to the market when I [saw / was seeing] her."
Answers: was running; saw. The meaning of the sentence changes drastically when using "ran" versus "was running". With "ran," the sentence means that Gloria saw me and ran to a market, as if to get away from me with "was running", the sentence means Gloria was heading to the market at the same time that I saw her. The word "when" is also a clue to use the simple form of the verb, so the form "saw" is correct for second part.
In the sentence "Tom thinks that that apple is rotten," what grammatical function is the second "that"?
The second "that" is a demonstrative adjective. The first "that" is a conjunction and can be eliminated from the sentence without losing meaning. The second "that", however, is referring to the word apple and is therefore a demonstrative adjective.
