@NOTFLIPPANT @neno16 if you want a better response, I suggest typing the writing questions exactly as written.
Both sentences have multiple errors, ranging from capitalization to comma usage to the use of the word “prospective” (prospective is an adjective; you probably mean perspective).
I wrote down the questions as it was.
@NOTFLIPPANT No, I mean letter for letter, including capitalization and punctuation as it is shown in the question. Try to get that right when asking for writing help.
The following example is essentially what you wrote but with proper capitalization:
(From) the (prospective) of serious (student of) Hispanic American history the new appointment of Professor Lopez to the history department was a (boon). (No error)
However, I will bet you that the writing question looked like this:
(From) the (perspective) of serious (students of) Hispanic American history, the new appointment of Professor Lopez to the history department was a (boon). (No error)
In this case, the error would likely be “perspective,” as it should be “perspectives,” unless we lived in a society where all students shared one common perspective.
No. This question is from 2008 may ( sunday), and i wrote the question correctly. After recieving explanation from pwnthesat, i found that it was diction error.
Prospective vs perspective
@NOTFLIPPANT Okay, I’ll take your word for that.
The sentence still contains more than one error. Besides lack of capitalization, shouldn’t “student” be changed to “students?” Shouldn’t there be a comma after “history?” This is why I suggest typing down writing/grammatical questions exactly as written, character for character.
Twine, not twin. To me, the wording and meaning of this sentence seems awkward, since when I try to parse the sentence, I obtain something like, “In the past, children had the option of entertaining themselves with kitchen pots and balls of twine, or playing with high-priced electronic toys.” Except high-priced electronic toys didn’t exist in the 1800’s/1900’s, so the meaning of this sentence probably wasn’t the intended one.
There are probably other reasons too that other CC users might find, but I also like choice C.
