In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts-P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
The spacecraft initiated descent towards the red planet.
P: The data gathered during this process will aid future missions.
Q: The heat shield protected it from atmospheric entry.
R: Soon after, the parachutes deployed successfully.
S: Engineers monitored every second of the landing sequence.
6. This landing marked a historic step in interplanetary exploration.
Show answer & explanation
Correct answer: B
Explanation
The most logical order for the sentence parts is QSRP.
Here is the breakdown of the sequence based on the chronological stages of a planetary landing:
1 (Introduction): "The spacecraft initiated descent towards the red planet."
Q: "The heat shield protected it from atmospheric entry." (This is the immediate first step upon entering an atmosphere).
S: "Engineers monitored every second of the landing sequence." (Continuous monitoring occurs as the craft descends).
R: "Soon after, the parachutes deployed successfully." (Parachutes deploy after the initial heat shield phase to slow the craft further).
P: "The data gathered during this process will aid future missions." (Refers back to the entire "process" just described).
6 (Conclusion): "This landing marked a historic step in interplanetary exploration."
