In 14.1, the first sentence offer support for the second sentence, that's why we can confidently reach our conclusion(using language like "clearly then"). In 11.1, there is no conclusion. A conclusion is basically a claim that is supported, but each sentence is a stand alone sentence simply stating fact. None of the sentences offer support to the other.

I just want to correct one thing: According to The Loophole in Logical Reasoning by Ellen Cassidy, you NEVER question the premise. It could be the most ridiculous thing but you have to accept the premise as true. It is the conclusion we question. If the premise does not support the conclusion, then we have to find the assumption.
