The correct pairs are AF, BD, and CE. AF - The part of speech used in A before AND is a noun (DIVERSITY) , therefore the part of speech used after AND should also be a noun. The noun INCLUSIVITY given in F is a suitable match here. The sentence conveys that most of the time, the responsibility for increasing diversity and inclusivity falls on people belonging to underrepresented groups. "Too often, the burden of work involved in increasing diversity and inclusivity falls on those from under-represented groups." BD - The use of infinitive TO makes it important that a base form verb comes after it. The verb RELY given in D is a suitable match. The sentence seeks to convey that everyone should work towards increasing diversity, and it is neither sustainable nor fair to depend on a few volunteers to do this important work. "Increasing diversity is a job for everyone and it is not sustainable or fair to rely on a small number of volunteers to do this important work” CE- The part of speech used in C before AND is a verb (MIMIC) ; therefore, the part of speech used after AND should also be a VERB. The verb PERPETUATE given in E is a suitable match here. The sentence seeks to convey that there are multiple criticisms of AI algorithms that copy and continue the biases of a wider society. "There have been many high-profile criticisms of AI algorithms that mimic , and so perpetuate, the biases of wider society”. Thus, E is the right answer.
