1. Count Rumford is perhaps best known for his observations on the nature of heat.

Show Hint
- ABCD
- CBDA
- ADCB
- CDAB
The Correct Option is C
Solution and Explanation
(A) follows naturally — he conducted experiments on frictional heat.
(D) offers a real observation — heat generated during boring.
(C) sets the scientific background — "caloric" theory by Lavoisier.
(B) connects that theory to Rumford’s scenario — caloric being squeezed out of metal.
Sentence 6 finally expresses Rumford’s doubt about the caloric explanation.
Thus, the proper flow is:
1 — A — D — C — B — 6
ADCB

- The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.
Certain codes may, of course, be so widely distributed in a specific language community or culture, and be learned at so early an age, that they appear not to be constructed – the effect of an articulation between sign and referent – but to be ‘naturally’ given. Simple visual signs appear to have achieved a ‘near-universality’ in this sense: though evidence remains that even apparently ‘natural’ visual codes are culture specific. However, this does not mean that no codes have intervened; rather, that the codes have been profoundly naturalized. The operation of naturalized codes reveals not the transparency and ‘naturalness’ of language but the depth, the habituation and the near-universality of the codes in use. They produce apparently ‘natural’ recognitions. This has the (ideological) effect of concealing the practices of coding which are present.- CAT - 2024
