A second-generation Japanese American, Wataru Misaka ______ in World War II (1941-45) and won two amateur national
basketball championships at the University of Utah when he joined the New York Knicks for the 1947-48 season, becoming
the ﬁrst non-white basketball player in the US’s top professional league.
already served
was already serving
already serves
had already served
Choice D is the best answer. Misaka served in World War II before he joined the New York Knicks in 1947. To show that a
past occurrence took place before another past occurrence, we need to use “had” + the past tense form of the verb. This is
called the past perfect tense.
Choice A is incorrect. Misaka served in World War II before he joined the Knicks. Both events are in the past, but his service
in World War II happened earlier, so we need a verb that makes it clear that his service (and the two national championships)
had ended by the time he joined the Knicks. Choice B is incorrect. “Was already serving” forms the continuous past tense,
which we use when we’re showing a past action that was ongoing. Misaka served in World War II before he joined the
Knicks. Both events are in the past, but they’re not happening at the same time, so we shouldn’t use the continuous past
tense here. Choice C is incorrect. Misaka served in World War II in the past, so we shouldn’t use the present tense “serves.”
