Question:

Directions: Each question consists of five statements followed by options consisting of three statements put together in a specific order. Choose the option which indicates a valid argument, that is, where the third statement is a conclusion drawn from the preceding two statements.

Example:
A. All cigarettes are hazardous to health.
B. Brand X is a cigarette.
C. Brand X is hazardous to health.

Here, ABC is a valid option, where statement C can be concluded from statements A and B.

A. Modern industry is technology-driven.
B. BTI is a modern industry.
C. BTI is technology-driven.
D. BTI may be technology-driven
E. Technology driven industry is modern.

Explanation:

(a) ABC is the correct answer choice, as it forms a valid syllogism.

BTI = BTI
MI = Modern Industry
TD = Thing that is technology-driven
All modern industries are technology-driven.
BTI is a modern industry
Therefore, BTI is technology-driven.
(b) ABD is invalid, although it is similar to the correct option ABC.

It is invalid simply because the statement D: ‘BTI may be technology-driven, is a tantalogous statement (that
is, it is always true, regardless of what the premises say).
(c) BCA is invalid. Just because BTI is a modern industry and it is technology-driven, it does not mean that all MI are TD. It would, however, be valid to conclude that ‘Some MI are TD’.
(d) EBC is invalid, because if BTI is a modern industry, we cannot definitely conclude that it is technologydriven, as evident from the Venn diagram.
