Explanation
There are many rules for correct writing. One of them states that when quotation marks are used, the period at the end of the sentence must be placed within quotation marks. On the other hand, another grammar rule states that when an introductory sentence is given, it must be separated from the quotation by a comma. According to the above rules, the correct answer is A. because the introductory part "The captain said" is separated from the second part of the sentence using a comma. Also, the second part of the sentence that is between the quotation marks, places the final period within the quotation marks. So the correct answer is A. The captain said, "But he needn't come round when you are on watch, Mr. Brown."
Answer: N. Scott Momaday - who is a native American himself - finds ironic that white people claimed that they were arriving into the "new world" when in reality there were ancient civilizations already living on those lands, and this claim is one that they have continued to sustain up to this day.
When Europeans arrived in 1492, there were very large Indian populations scattered all across America with a rich history and culture, an element that vastly defers the logic of the discovery of a "new world".
The sentence that has an error in subject-verb agreement is D. The man, in the next apartment, as well as the people across the hall, have lived in the building since 1960.
Subject-verb agreement means that the subject of a sentence and the verb must agree in number. That is to say, both of them need to be singular or plural. In sentence D, the subject of the sentence is "the man" and the verb is "have lived". As the sentence refers to one man, the verb should be "has lived" in order to agree in number with the subject.
