Given question consists of six sentences of a passage. The first and sixth sentences are given as (S1) and (S6). The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences.
S1: Gaganyaan is a national programme wherein ISRO is leveraging the domain expertise of various agencies for expediting its execution.
S6: It will lay the foundation for a sustained Indian human space exploration programme in the long run.
P: With this programme, a new vertical has been created within ISRO to steer this growth.
Q: The Gaganyaan Programme marks an inflection point in the growth profile of India's space endeavour.
R: This new vertical envisages undertaking the demonstration of human space flight to Low Earth Orbit in the short-term.
S: A new ISRO centre, Human Spaceflight Centre has been formed for Low Earth Orbit flights. The correct sequence should be:

Correct option is A

The correct sequence for the middle sentences in this passage, (a) QPRS, aligns as follows:
· Q (The Gaganyaan Programme marks an inflection point in the growth profile of India's space endeavour) should naturally follow S1, as it defines the significance and transformative nature of the Gaganyaan programme in the context of India’s overall space activities. It establishes the pivotal role of the programme.
· P (With this programme, a new vertical has been created within ISRO to steer this growth) logically follows Q. This sentence explains the structural response within ISRO to the inflection point noted in Q, introducing a new vertical designed specifically to steer the growth brought about by the Gaganyaan programme.
· R (This new vertical envisages undertaking the demonstration of human space flight to Low Earth Orbit in the short-term) follows P and details the specific objectives of the newly created vertical. It outlines what this vertical is tasked with in the near future, connecting the structural organization within ISRO to specific mission goals.
· S (A new ISRO centre, Human Spaceflight Centre has been formed for Low Earth Orbit flights) is the logical continuation from R, as it provides more detail about the actual establishment created under the new vertical. It describes the dedicated center formed to execute the low Earth orbit flights discussed in R.
This arrangement (QPRS) effectively progresses from establishing the programme's importance to detailing the organizational changes and specific objectives, culminating in the setup of a specialized center, thereby providing a comprehensive narrative that leads to the foundational role of Gaganyaan in future space exploration as noted in (S6).
