So i was wrong in thinking that the wheel rolled 100 meter at the given rate (statement 2), but statement 2 actually gives the rate only, not the rate at which it covers 100 meter.

''Argument essay template'' -still applicable?
I just saw this post 'Argument essay template, if anyone wants it'. My questions are:
1) Is it still applicable?
2) Is it considered plagiarism if anyone follows this format and writes A to Z from the conclusion/all general sentences part?

Hi, With the remaining options, we can now focus on what the Neanderthal did IN THE PAST. Answers A and C don't include the necessary past tense verb(s) that we need (they also use the word "as" incorrectly). I did not get the point you made about past tense verbs. Would appreciate much if...
