Set 2: Central Ideas (Advanced)

Explanation

Answer: B

PASSAGE

The following text describes the 'Turing Test'. Proposed by Alan Turing in 1950, the Turing Test is a measure of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. The test involves a human evaluator who engages in natural language conversations with a human and a machine designed to generate human-like responses. The evaluator is aware that one of the two partners is a machine. If the evaluator cannot reliably tell the machine from the human, the machine is said to have passed the test.

What is the criterion for a machine passing the Turing Test?

A. The machine must solve complex mathematical problems faster than the human
B. The machine must reveal it is a robot✓ Correct
C. The human evaluator cannot reliably distinguish the machine's responses from the human's
D. The machine must physically resemble a human

Detailed Explanation

Choice C is correct. The text states: 'If the evaluator cannot reliably tell the machine from the human, the machine is said to have passed.'

Key Evidence:

• "evaluator cannot reliably tell the machine from the human"

• "indistinguishable from... a human"

Why others are wrong: A (Inaccurate (Test is about conversation/imitation, not speed)), B (Opposite), D (Inaccurate (Text specifies 'natural language conversations', not physical form)).
