Rearrange the parts of the sentence in correct order.
While infection can
P. potentially cause severe disease
Q. and can kill, timely treatment
R. with commonly available antibiotics
S. should clear the infection

Correct option is A

Option (a) is the correct order of the given sentences.
Explanation of the correct sequence (PQRS):
Let’s reconstruct the full sentence using option (a):
"While infection can potentially cause severe disease and can kill, timely treatment with commonly available antibiotics should clear the infection."
Here’s why this order is correct:
· P. "potentially cause severe disease"
· → This is the direct continuation of “While infection can…”, expressing the possible consequence of an infection.
· Q. "and can kill, timely treatment"
· → Extends the consequence further — "can kill" — and transitions to a contrast by starting "timely treatment..."
· R. "with commonly available antibiotics"
· → Modifies "timely treatment" by specifying the kind of treatment.
· S. "should clear the infection"
· → Concludes the sentence with the expected result of the treatment.
Logical Flow Summary:
· While infection can → P (cause disease)
· → Q (and can kill, but…)
· → R (treatment with antibiotics)
· → S (clears the infection)
Why other options are incorrect:
· (b) QSPR – Begins with “and can kill” without explaining what the infection does first — illogical without P.
· (c) QRPS – Starts with “with antibiotics…” right after “infection can”, which doesn't connect grammatically.
· (d) PSQR – Jumps from disease to treatment without completing the contrast using "and can kill", making the sentence sound abrupt.
