Arrange the sentences in the right order to make a paragraph.
P. A vaccine trains the body to fight a disease before it strikes.
Q. If the real germ ever enters, these defences destroy it quickly.
R. It does this by showing the body a harmless form or part of the germ.
S. The body learns to recognise the germ and makes defences against it.

CorrectNot quiteAnswer D

Correct answer: D

P opens: it says what a vaccine does. R says how "it does this".
S says what the body learns from the harmless germ, and Q says what "these defences" do later.
So the order is PRSQ.

Worth noting

RPSQ opens with "it does this", which points back to something that has not been said.
