Sentence rearrangement (PQRS): Order the parts to show how easy it is to convince oneself that a poorly understood phrase means more than it does; choose the correct sequence.

Given data

• Starter: 'It is very easy'
• S: to persuade oneself
• R: that a phrase that one does not quite understand
• Q: may mean
• P: a great deal more than one realises

Concept/Approach
Use the pattern 'easy + to-infinitive' then a 'that'-clause with predicate and its complement phrase.

Step-by-step reconstruction
Construct: 'It is very easy to persuade oneself that a phrase that one does not quite understand may mean a great deal more than one realises.'Sequence: SRQP.

Verification
All complements are in standard order; the sentence reads idiomatically.

Common pitfalls
Beginning with R produces a heavy clause before the easy-to construction; placing P before Q breaks verb–object flow.

Final Answer
Correct order: SRQP.
