1. B. remarks - The word "some" in the sentence implies that the word in the blank will be plural. "Some remarks." 2. A. an impression - This is a standard English phrase. You make an impression on people, even if it's multiple people. "Making impressions on people" sounds a bit unnatural.

1. "Remarks" because you have used the word "some," implying that more than one remark was made, the plural word "remarks" is necessary. 2. "an impression" I believe that either "an impression" or "impressions" could be correct here, depending upon what the sentence is saying. However, "an impression" is what you are most likely to hear in common use.

1. Remarks. The preceding word 'some' should be the clue that remarks is plural (more than one remark) 2. An impression.
