Challenging
A writer is debating the punctuation of 'a brilliant emotional performance.' While the adjectives can be rearranged, some might argue their relationship is nuanced. What is the strongest argument, based on the tutorial's tests, for using a comma?
A.comma is required because both the 'and' test ('brilliant and emotional') and the rearrangement test ('emotional, brilliant') produce grammatically sound and meaningful phrases.
B.No comma should be used because 'emotional' specifies the type of performance, and 'brilliant' describes the quality of that specific type.
C.comma is optional because the meaning does not change significantly with or without it.
D.comma is required only if the writer wants to create a dramatic pause for the reader.
Challenging
A student justifies not using a comma in 'the big red ball' by stating, 'The 'and' test works because 'the big and red ball' sounds fine.' What is the primary flaw in this student's reasoning?
A.The 'and' test is not applicable to adjectives of color and size.
B.The student failed to apply the rearrangement test, which fails ('the red big ball' is awkward), indicating the adjectives are cumulative.
C.The student is correct; if the 'and' test works, no comma is ever needed.
D.The 'and' test only works if the sentence also contains adverbs.
