Each item consists of six sentences of a passage. The first and sixth sentences are given as S1 and S6. The middle four sentences have been jumbled up and labelled as P, Q, R and S. Find the proper sequence.
S1: "Every person carries in his head a mental model of the world — a subjective representation of external reality," writes Alvin Toffler in Future Shock.
S6: When we begin to think we can do so only because our mind is already filled with all sorts of ideas with which to think.
P: It organizes our knowledge and gives us a place from which to argue.
Q: This mental model is, he says, like a giant filing cabinet.
R: It contains a slot for every item of information coming to us.
S: As E.F. Schumacher says, "When we think, we do not just think; we think ideas.
The correct sequence should be
- APSRQ
- BSPRQ
- CQRPS
- DRQPS
Explanation
Q introduces the filing-cabinet simile, R describes its slots, and P its organizing function; then S's Schumacher quote about 'think[ing] ideas' leads naturally into S6's 'mind... filled with all sorts of ideas with which to think.' QRPS is the only coherent chain; the other orders break the simile or the quote's link to S6.
