1-C

Option (a) cannot be inferred from the passage. Nothing

is mentioned about examining components of

intelligence in functional isolation. Option (b) is negated

by “In the elementary constituents of the brain, down

to the level of the nerve cells, there is the presence of

the rules.” Option (d) does not follow from the

passage. Hofstadter opines that intelligence might be

brain bound, but “it can be lifted right out of the

hardware in which it resides.” Option (c) is correct; it

can be inferred from the lines “he infers that in relation

to.…….a “Within” in the heart of things”.

2- D

Options (a), (b) and (c) can be inferred from the

passage. Hofstadter draws an analogy between ant

teams in a colony and brain states. He further states

that these teams are “low-level active sub-systems

of a complex system”. It is also mentioned in the

passage that Hofstadter likens ant teams to signals.

Option (d) cannot be concluded from the passage.

Refer to the lines “Ultimately, the fully evolved ant

colony takes on a holistic aspect, and emerging

molecular mechanisms take form”. Here, the analogy

is between the holistic aspect of a fully developed ant

colony and emergent molecular mechanisms in the

brain. Individual ants have not been compared to such

mechanisms.

3- B

The passage talks about “information and its various

expressions” as a pivot that configures intelligence.

While it’s mentioned that “In the elementary constituents

of the brain, down to the level of the nerve cells, there

is the presence of the rules”, it is not claimed that

intelligence operates according to simple rules. Hence,

option (a) is negated. It cannot be concluded that

intelligence can have several expressions thus option

(c) is also negated. Option (b) comes directly from the

passage as the passage mentions that intelligence

(though resides in the brain hardware and is thus

brain bound) can be lifted out. Thus, it can be

conceptualised separately from brain hardware which

houses it.
