OG12-16的解释:Verb form; Logical predication
The sentence explains the expectations that resulted from a past retail sales trend. Since expectations look to the future but are not yet realized, the relative clause explaining these expectations should be conditional, employing the auxiliary verb would.
A The simple past-tense verb form does not express the forward-looking sense of expectations.
B Correct. By using the verb would double, this concise sentence indicates that the expectation has not yet been realized.
C This construction is awkward, announcing the topic (personal spending) and then elaborating in a relative clause that restates this topic as it.
D Although this option is not technically wrong, it is less clear and graceful than B.
E Like option C, this sentence is awkward and unnecessarily wordy, announcing the topic and then using an additional clause to elaborate on it.
