The tutorial states 'Effect' is *almost always* a noun. However, a student correctly writes: 'The new school board hopes to effect major changes in the curriculum.' Why is 'effect' the correct verb in this specific sentence?

C.It is an archaic usage that is no longer considered correct.
D.It is a specific verb meaning 'to bring about' or 'to cause to happen.'
Challenging

Their are other narrative choices, but this one is most effective.' Which error most significantly undermines the analytical credibility of the paragraph?
A.The use of 'Their' instead of 'There,' because it confuses possession with location.
B.The use of 'personal,' because it is too vague for a literary analysis.
C.The use of 'affect' instead of 'effect,' because it misidentifies the core concept of cause and result in the main argument.
D.The lack of a possessive apostrophe on 'authors,' because it is a basic punctuation error.
