Which one of the following statements is the most logical and rational inference that can be made from the above passage?
Answer & explanation
Answer: (d) As we go digital, we must recognise the huge threat to Internet security from some IoT devices.
Low-end IoT devices stay cheap by leaving security out, and they are multiplying fast; the passage ends on 'daunting' security challenges. The sound inference is that going digital means recognising the security threat from such devices.
- ✗ (a) India, manufacturing and 'enabling technologies' are not discussed at all.
- ✗ (b) India is never mentioned, and the passage does not advise holding back; it expects the IoT 'to expand exponentially'.
- ✗ (c) Convenience devices are listed, but comfort is not the point; the passage stresses the security cost of cheapness.
- ✓ (d) Security is skipped to keep costs low, the devices are spreading everywhere, and the challenges are 'daunting' — so the threat must be recognised. 'Some IoT devices' keeps the claim to the low-end class described.
Remember · The inference usually rests on the passage's closing concern; options naming a country or sector the passage never mentions go first.
