Europe, America and Japan have taken to the field of science with SINGULAR vigour and activity.

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.
