653. Slips of the tongue do not necessarily reveal concealed beliefs or intentions but rather are the result from the competition between various processing mechanisms in the brain.

(A) but rather are the result from
(B) and instead are the result from
(C) being rather the result of
(D) and rather result from
(E) but rather result from

Solution:

Parallelism

In A and B, “the result” is a noun. If “result” is noun then it must be written as “the result of”. If “result” is a verb then it must be written as “rather result from”.
In C, “being” makes the sentence unnecessarily passive.
In D, use of “and” is incorrect because there is a contrast shown in the sentence and hence, conjunction “but” must be used.
In E, “Slips… reveal… but rather result from…” maintains parallelism.
E is the best choice.
