Question

In the following items, there are four sentences. Which one of the following is the correct sequence?
A. with petrol engines people were able to build motor cars and aeroplanes
B. James Watt used the power of steam to drive machines
C. then, many years later, the petrol engine was invented
D. his invention was used later by other clever men to give us the railway engine
E. these provided quicker means of travelling
Choose the correct answer from the options given below:

• A. A, B, C, D, E
• B. A, B, D, C, E
• C. B, D, C, E, A
• D. B, D, C, A, E

Hint:

Follow the timeline of technology:
Steam power (B) $\rightarrow$ Steam trains (D) $\rightarrow$ Invention of petrol engine (C) $\rightarrow$ Cars and planes (A) $\rightarrow$ Impact on travel speed (E).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
To arrange these historical and technological developments in the correct logical sequence, we should follow the chronological order of the inventions.

Step 2: Detailed Explanation:
Let us analyze the chronological order of the industrial and transportation milestones mentioned in the sentences:
- Sentence B ("James Watt used the power of steam to drive machines") introduces the first major milestone: the development of the steam engine in the late 18th century. This is the logical starting point of our sequence.
- Sentence D ("his invention was used later by other clever men to give us the railway engine") builds directly on James Watt's work.
The phrase "his invention" refers back to the steam engine introduced in B, indicating that D must follow B (B $\rightarrow$ D).
- Sentence C ("then, many years later, the petrol engine was invented") introduces the next major technological leap: the internal combustion engine in the late 19th century.
The transition phrase "then, many years later" confirms that C follows the steam-era events in B and D.
- Sentence A ("with petrol engines people were able to build motor cars and aeroplanes") describes the applications of the newly invented petrol engine.
Since it mentions the use of "petrol engines," it must follow the invention of the engine described in C (C $\rightarrow$ A).
- Sentence E ("these provided quicker means of travelling") refers back to the "motor cars and aeroplanes" introduced in A.
The pronoun "these" links directly to the vehicles in A, making E the final sentence in the sequence.
Combining these steps, the logical chronological sequence is B $\rightarrow$ D $\rightarrow$ C $\rightarrow$ A $\rightarrow$ E.

Step 3: Final Answer:
The correct chronological sequence is B, D, C, A, E.
