Verified Answer
Read the following information carefully and answer the question give...
It cannot be determined since we not know the exact information regarding their age
Because some people have the same age.
Only two persons were left behind by Q.
S was the last one to finish the race.
Q is either of the same age or older than T but completed the race before her.
Only one person is behind T.
Based on the given information, we can decide the finishing order of race by the persons.(in ascending order of their position.)
P > R > Q > T > S ....... (i)
S is younger than only Q and T.
P is either equal to or older than only R.
Q is either of the same age or older than T.
Based on the given information, we can decide the order as per the age of the persons.
Q ≥ T > S > P ≥ R .......(ii)
The one who is first in the race is not the youngest.
From (i) and (ii), it is clear that R did not stand first in the race, while P is first as he is not the youngest.
Thus the order of finishing the race - P > R > Q > T > S
Order of age - Q ≥ T > S > P ≥ R

PASSAGE IIIThe need for Competition Law becomes more evident when foreign direct investment (FDI) is liberalised. The impact of FDI is not always pro-competitive. Very often FDI takes the form of a foreign corporation acquiring a domestic enterprise or establishing a joint venture with one. By making such an acquisition the foreign investor may substantially lessen competition and gain a dominant position in the relevant market, thus charging higher prices. Another scenario is where the affiliates of two separate multinational companies (MNCs) have been established in competition with one another in a particular developing economy, following the liberisation of FDI. Subsequently, the parent companies overseas merge. With the affiliates no longer remaining independent, competition in the host country may be artificially inflated. Most of these adverse consequences of mergers and acquisitions by MNCs can be avoided if an effective competition law is in place. Also, an economy that has implemented an effective competition law is in a better position to attract FDI than one that has not. This is not just because most MNCs are expected to be accustomed to the operation of such a law in their home countries and know how to deal with such concerns but also that MNCs expect competition authorities to ensure a level playing field between domestic and foreign firms.Q. With reference to the passage, consider the following statements:1. It is desirable that the impact of Foreign Direct investment should be pro-competitive.2. The entry of foreign investors invariably leads to the inflated prices in domestic markets.Which of the statements given above is/are correct?
