Question

source: jim murphy, truce: the day the soldiers stopped fighting, page 16. published by scholastic, 2009:
by mid-august, fighting was taking place in many locations all over europe. meanwhile, enlistment centers in every country involved were crowded with eager volunteers clamoring to get into battle as quickly as possible.
student text:
by august 1914, world war i had begun, and impatient young men all over europe were more than ready to join the fight (murphy 16).
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 rephrased the source content (changing "eager volunteers clamoring to get into battle" to "impatient young men... more than ready to join the fight") and properly cited the source with (Murphy 16). No direct, unquoted copying of the source's exact phrasing occurred.

Answer:

No, it is not plagiarized.
