1-C

The opening paragraph mentions the reason for the ‘biological

machinery’ predating the emergence of languages. All the

other options come after the emergence of language. This

makes (c) the correct answer choice.

2-C 

The Baldwin theory describes the process of natural selection

wherein “callus development became triggered within the

embryo and could occur without environmental stimulation”.

The diminishing of the exterior tail in humans is akin to this

process as the diminishing of the tail is a process of natural

selection. All the other options are sensory in nature and

hence are incorrect.

3- B

Language remains driven by culture. The passage centers on

the theme that culture is largely responsible for the evolution

of language. Options (a) and (d) are not correct because

biology and genetics have nothing to do with the evolution of

language. Options (c) is also ruled out as is it a part of the

language.
