Which of the following research questions is too broad? Early Kingdoms of West Africa
Ulysses S. grant: A Failure as President?
The Colonization of the Middle Atlantic States
Communication Through the Ages

The broad topic would be Communication Through the Ages.  Early Kingdoms narrows it down to West Africa.  A short research project could give you the info you need on USGrant.  The Mid Atlantic States are such a small portion that when you study colonization, it can be narrowed down to each colony.  Communiciation Through the Ages - is just that - a long time and a very broad subject.  From when to when?  

Explanation:

It would take a while to research all the different types of communication - and is it narrowed down to technology or can it go back even to the stone age and how people drew pictures to communicate???

the narrator is saying that the old lady made her feel uncomfortable. you know this because they say "i found that rather irksome", "perhaps it was her being so upright and trim", and "i don't think it was that, because i thought that quaintly pleasant." hope this !

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.
