In the following question a statement is given followed by two courses of action. A course of action is taken for improvement, follow-up, etc. Read the statement carefully and give answer 1) if only course of action I follows. 2) if only course of action II follows. 3) if either course of action I or II follows. 4) if both courses of action I and II follow 5) if neither course of action I nor II follows. Statements: Large number of college students are found to be focusing more on fashion than on studies. Courses of action: I. Colleges should impose restrictions on use of fashionable clothes and accessories. II. Colleges should keep the students busy enough with studies, so that they don't find time for other things like fashion.

Nitrogen forms the largest number of oxides as it is capable of forming stable multiple bonds with oxygen. They range of N_(2)O (O.S of nitrogen +1) through NO, N_(2)O_(3),NO_(2),N_(2)O_(4) "to" N_(2)O_(5) (O.S of nitrogen +5). Following points are improtant regarding the study of oxides of nitrogen. (a) All oxides of nitrogen expect N_(2)O_(5) are endothermic as a large amount of energy is required to dissociate the stable molecule of oxygen and nitrogen. (b) The small electronegativity difference between oxygen and nitrogen make N-O bond easily breakle to give oxygen and hence oxides of nitrogen are said to be better oxidising agents. (c) Expect N_(2)O_(5) , all are gases at ordinary temperature. N_(2)O_(3) is stable only at lower temperature (253K). (d) Expect N_(2)O and NO which are neutal oxides, all are acidic oxides which dissolve in water forming coresponding oxy acids. (e) They are also good example for illustrating the concept of resonance. The gas which is acidic in nature is :

Daily consumption of a certain form of curcumin improved memory and mood in people with mild, age-related memory loss. The research examined the effects of an easily absorbed curcumin supplement on memory performance in people without dementia, as well as curcumin's potential impact on the microscopic plaques and tangled in the brains of people with Alzheimer's disease. Found in turmeric, curcumin has previously been shown to have anti-inflammatory and antioxidant properties in laboratory studies. It has also been suggested as a possible reason that senior citizens in India, where curcumin is a dietary staple, have a lower prevalence of Alzheimer's disease and better cognitive performance. Which of the following statements are true ? 1. Senior citizens in India have high level of Alzheimer's disease because of consumption of turmeric. 2. Senior citizens in India do not have high prevalence of Alzheimer's because of consumption of turmeric. 3. Consumption of turmeric enhances cognitive performance. 4. Curcumin is an antioxidant. Select the correct answer using the code given below:

If the US software companies choose Indians and not American blacks, it has nothing to do with colour and everything to do with talent. Had it been a racist ploy, companies would have imported only whites from Eastern Europe, not Asians. Which of the following, if true, most seriously strengthens the argument given above? 1) Black American professionals are lobbying the US Congress to stop granting visas to Indian software experts. 2) Europe and Japan have been left far behind in information technology precisely because they resist the infusion of skilled Indians. 3) Choosing top-class Indian professionals does not amount to segregating blacks or preventing them from voting. 4) The number of H-1B visas for Indian infotech professionals could rise from 115,000 this year to 200,000 next year. 5) Three states with the highest demand for H-1B visas have all taken steps to reduce African-American and Latino enrolment in their colleges.
