Para-jumble (sentence arrangement): Arrange the sentences to build a clear argument about how to grow old wisely, linking dangers to the recommended mindset. S1 = "The art of growing old is one which the passage of time has forced upon my attention." S6 = "This is not always easy one's own past is gradually increasing weight." Between S1 and S6, place the fragments in a logically persuasive order: P = "One of these is undue absorption in the past." Q = "One's thought must be directed to the future and to things about which there is something to be done." R = "Psychologically, there are two dangers to be guarded against in old age." S = "It does not do to live in memories, in regrets for the good old days, or in sadness about friend who are dead." Choose the correct sequence of P–Q–R–S that completes the paragraph.

Given data

• S1 introduces the theme of growing old.
• R names two psychological dangers in old age.
• P identifies one danger: undue absorption in the past.
• S elaborates on living in memories and regrets.
• Q prescribes the remedy: orient thoughts to the future.
• S6 concedes it is hard because one's past grows heavier.

Concept / Approach
Move from theme → dangers → specific danger → elaboration → remedy → concession. R must follow S1 to announce the structural frame ('two dangers'). P and S form a tight pair (label + explanation). Q gives the forward-looking corrective, which naturally precedes S6's realistic caveat.

Step-by-step
S1 + R → frame the two dangers.… + P → state danger #1 (absorption in the past).… + S → explain why dwelling on the past is harmful.… + Q → provide the remedy (future orientation).… + S6 → acknowledge difficulty.

Rejecting distractors
QSRP / QPRS put the remedy before identifying the danger.RPQS skips S's crucial elaboration before prescribing Q.
