Question

compare the student text with the source.
source: charles bethea, \two of the worlds greatest shooters consider the four-point shot.\ published in the new yorker, 2016:
of course, the three-pointer, like the miniskirt, was once a shocking idea, too. the american basketball association, which merged with the n.b.a. in 1976, was the first major basketball league to adopt it.
student text:
three-point shots in basketball—like miniskirts—were once considered controversial.
is the student text plagiarized?
no, it is not plagiarized.
yes, because it fails to use quotation marks.
yes, because it fails to cite the source.

Explanation:

The student text rephrases the core comparison from the source (three-pointers/miniskirts as once shocking/controversial) using different wording, and this is a short, common paraphrase of a simple analogy without copying exact phrasing that would require quotation. It does not meet the criteria for plagiarism.

Answer:

No, it is not plagiarized.
