Explanation for Question 21 From the Writing Section on the 2017 May Sat
Question 21 is another punctuation question. 2 And it's asking us what correct punctuation do we need after the word historian, 3 we have the option of a dash, no punctuation, 4 a comma or a semi-colon let's read the question or the sentence that we 5 have in order to understand what needs to be there. 6 The sentence goes K Williams or British historian believes that filmmakers 7 have a great responsibility. So whatever perpetration we do have is 8 going to be ending a phrase that started by the first comma. 9 So Kate Williams, comma or British historian blank. 10 So this brace right here. Now we definitely know then that we do 11 need a comma because we are separating a British historian from beliefs. 12 Um, a British historian is just defining or further explaining cool. 13 Kate Williams is so we know we need a comma or a punctuation. 14 And in fact, we do need a comma. 15 Now, the reason why we need a comma and we can't have a dash 16 is because we started the phrase off with a comma. 17 And the sat just like grammar in general is very particularly particular about 18 consistency. It has to match. 19 If we start a phrase with a comma, we have to finish that place 20 of the comma. If we had started it with a dash, 21 which would be fine, we would just also have to end it with a 22 dash. So since we're starting with a comma, 23 we've finished it with a comma and that's C historian, 24 common beliefs.
