Question : Given below are four sentences, three of which, are jumbled. Pick the option that gives the correct order.
A. For example, though there is a close relation between invention and science and engineering, an inventor is not necessarily a scientist or an engineer. B. An engineer, on the other hand, uses existing technology and scientific understanding to design better objects or processes, but an inventor creates something that had never previously existed.
C. Inventors defy definition; as a result, they are frequently defined by what they are not.
D. A scientist is said to be a discoverer-that is, somebody who by acute observation and brilliant analysis is able to find and explain something that already exists in nature.

Solution : The correct choice is the third option .
The paragraph starts with sentence C , which introduces the idea that inventors are challenging to define and are often described by what they are not. It is followed by sentence A , which provides an example to illustrate the relationship between invention, science, and engineering, emphasising that an inventor is distinct from a scientist or engineer, followed by sentence D , which contrasts inventors with scientists, explaining the role of a scientist as a discoverer who explains things that already exist in nature. The paragraph concludes with sentence B , which contrasts inventors with engineers, highlighting the difference in their roles and the creative aspect of an inventor.
