Idiom + Rhetorical construction

This sentence depends on using the correct conjunction
            to join two independent clauses.
        In that is a conjunction
                that means inasmuch as; because
            in that has largely gone
            out of use, it is considered stilted and overly formal. It also
            uses two words when one would do. In this sentence, the
            second clause explains the first one, so the conjunction
        for, meaning because, is the most appropriate choice for joining the two independent clauses of the compound sentence.

而OG10 中in that成为了正确选项

208. Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.

(A)  because they are composed of tissues such as tooth and bone

(B)  because they are composed of tissues like tooth and bone that are

(C)  because they are composed of tissues, like tooth and bone, tissues

(D)  in that their composition, tissues such as tooth
                        and bone, is

(E)   in that
                            they are composed of tissues such as tooth
                        and bone, tissues

Only E, the best choice, clearly states that teratomas consist of tissues such as tooth and bone, and that such tissues are not normally found in the organ with the teratoma. Clear statement of this fact requires the repetition of tissues to establish the appositive--tissues normally found.... Without such repetition, A and B imprecisely state that the tooth and bone, as opposed to the tissues, are not normally found in the affected organ. Choices B and C alter the meaning with the use of like', that is, they suggest that the tissues are not tooth and bone, but only like them. The confused syntax of D states that their composition, not the tissues, is found in the organ....
