Fourier's law of heat conduction is (where Q = Amount of heat flow through the body in unit time, A = Surface area of heat flow, taken at right angles to the direction of heat flow, dT = Temperature difference on the two faces of the body, dx = Thickness of the body, through which the heat flows, taken along the direction of heat flow, and k = Thermal conductivity of the body)

The following sentences form a paragraph. The first and the last sentences of the paragraph are given. The rest of the sentences are numbered as P, Q, R and S. These four parts are not given in their proper order. Read the sentences and choose the alternative that arranges them in the correct order. 1. The concept of Globalisation by integrating nation states within the theme work of World Trade Organisation (WTO) is an alternative version of the Theory of Comparative Cost Advantage propagated by the classical economists for assuming unrestricted flow of goods between the countries for mutual benefit, especially from Great Britain to other less developed countries or to their colonies. P. However, the advocates of globalisation, especially from the developed countries purposely limit the definition of globalisation to only three components, i.e., unrestricted trade flows, capital flows and technology flows. Q. They do not want to include the free flow labour within the parameter of globalisation set by them. R. In this way, the imperialist nations gained much at the cost of the colonial countries who had to suffer from the scar of stagnation and poverty. S. The World Commission on the Social Dimension of Globalisation (WCSDG) set up by ILO has also made some important observations on globalisation. 6. In the meantime, various countries of the world have adopted the policy of globalisation.
The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. SI: Why do the English travel? S6: For here, in cosmopolitan England, one is always exposed to the danger of meeting all sorts of peculiar aliens. P: Besides, they are taught that travel broadens the mind. Q: They do so mainly because their neighbour does this and they have caught the bug from him. R: Although they have now discovered the sad truth that whatever travel may do to the mind, it certainly broadens other parts of the body. S: But, and perhaps mainly, they travel to avoid foreigners. The proper sequence should be
