OE:
Verb form; IdiomThis sentence asserts that a court decision has qualified a 1998 ruling. It
then goes on to explain the series of conditions stipulated by that ruling:
workers cannot be laid off if they have been given (prior) reason to
believe that continued satisfactory job performance will (always) ensure
that their jobs are safe. To express these complicated temporal
relationships, the present tense passive verb cannot be laid off describes
the assurance provided by the ruling; the present-perfect, passive verb
describes the prior condition have been given . . ., and the future tense
verb will be describes the outcome the workers can expect. The idiom
reason to believe succinctly describes the assurance given to workers.
A.
Correct. The sequence of conditions makes sense, and the idiom is
correct.
B. The present tense are given fails to clarify that the assurance of job
security must precede the workers’ confidence that they cannot be
laid off. The phrase reason for believing (singular, with no article) is
unidiomatic and in this context is inappropriate.
C. This version appears to be presenting having been given reason . . .
as a restrictive modifier of laid off. This makes the sentence very
awkward and hard to make sense of, and it obscures the requisite
nature of the condition (that workers had been given prior reason to
think their jobs were safe). Reason for believing is unidiomatic.
D. Without a comma after off, it is unclear what having been given
reason . . . modifies; the string of infinitive phrases is awkward and
confusing.
E. As in (D), it is unclear what the participial phrase (in this case, given
reason to believe) is supposed to modify.
The correct answer is A.
