(D) changes in the measured strain across a fault zone, and variations in

(E) changes in measurements of the strain across a fault zone, and variations among

Answer：

1. Choice C is best. In A and B, the plural pronouns their and they do not agree with the singular noun bank. B, like D and E, illogically shifts from the plural customers and funds to the singular check, as if the customers were jointly depositing only one check. In D, requires a bank that it should is ungrammatical; requires that a bank is the appropriate idiom. In E, the use of the passive construction is to be delayed is less informative than the active voice because the passive does not explicitly identify the bank as the agent responsible for the delay.

2. D, the best choice, describes the warning signs in parallel phrases. Despite surface appearances, the nouns changes and variations are parallel with tilting, but the verbal forms changing and varying in A, B, and C are not: tilting, one of the deformations of the Earth's crust, is used here as a noun that is parallel to fluctuations, whereas changing and varying are used as verbs indicating some action undertaken. Moreover, these verbs are used incorrectly because the sentence mentions no subject that is performing these actions. B and E illogically state that it is not the strain but the measurements that portend danger, and among in E wrongly suggests a comparison of different electrical properties rather than of different behaviors of the same properties.
