Questions Refer to the Passage Below

Questions refer to the passage below.
"The problem that now arises is quite simple. We [Singaporeans] are substituting for British authority our own. And we have got to devise a formula to ensure that the authority that ultimately emerges . . . is one that will command the loyalty, the support of the majority of all the various racial, linguistic groups in the country.
[Some] don't want a multi-racial society because they then have to compete on performance . . . We say these problems can only be resolved if you educate, and educate and grow a new generation of men trained in technological skills, thinking like you, like everybody else anywhere in any civilised society, rationally, calculating, prepared to make the effort on his own behalf. Then we begin to resolve our problems. And we are beginning to do these things. A slow process, maybe in one, two, three generations."
