og 212 212. The Baldrick Manufacturing Company has for several years followed a policy aimed at decreasing operating costs and improving the efficiency of its distribution system.
A. aimed at decreasing operating costs and improving B. aimed at the decreasing of operating costs and to improve C. aiming at the decreasing of operating costs and improving D. the aim of which is the decreasing of operating costs and improving E. with the aim to decrease operating costs and to improve
In E, the infinitives to decrease and to improve, while parallel, are less idiomatic than the prepositional phrase of decreasing ... and improving in modifying the noun aim. Also, with the aim...to improve can easily be construed as referring to the Baldrick Manufacturing Company and so does not refer unequivocally to policy.
the answer choices give you the option of replacing with different clors with whose different colors but the second options is wrong because , if you added whose, it could refer to the layers ofr the Canon, and whenever a pronoun has more than one possible antecedent, it is used incorrectly. Eliminate B and C. A is correct. Eliminate E as well because the subject of marking is similarly unclear; is it the layers or the Canyon that is marking the passage of time? And A is better than D because, once again, seen is better than the wordier alternative been able to see. A is correct.
