Rearrange the parts of the sentence in the correct order.
One element that
P. is timing, in particular ensuring that
Q. is essential to navigating deep space
R. the time on board spacecraft is synchronised
S. with the time on the ground
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. QPRS.
- In this corrected sequence, the sentence begins with "One element that is essential to navigating deep space," which establishes the main subject or concept being discussed. Thus, statement Q will follow the given part of the sentence.
- The next part, "is timing, in particular ensuring that," elaborates on the specific aspect that is crucial for deep space navigation. Thus, statement P will follow statement Q.
- Following that, the statement R i.e., "the time on board spacecraft is synchronized" provides specific details regarding the synchronization of time on spacecraft.
- Finally, the sentence S i.e., "with the time on the ground" further clarifies the synchronization by specifying that it is done with the time on the ground.
Therefore, the correct sentence would be:
One element that is essential to navigating deep space is timing, in particular ensuring that the time on board spacecraft is synchronised with the time on the ground.
