|"But keeping in mind that the abolition of scheme won't stop them from travelling by air". It can't be guessed at any cost. Because the reasons may be many, nt ly, the given reason. It should be option[d]. Na?|

|Which about do you like air ticketing and what is the meaning of air ticketing?|

|It doesn't necessarily imply "The students who resort to travel by air can bear the expenses of air ticket".
The action of the government may have been due to some other financial difficulties, not necessarily because students can afford.
The Government may have directed the funds to say disaster relief or emergency or war.

|Universal quantifier ranging over an empty domain of discourse gives a trivially true output. So I suppose you could say that it is implicit.
In the case that at least one student takes a flight, it is a necessary condition that he can afford it, hence the assumption is satisfied. If no student takes a flight, all students who did take a flight (that is none), could afford it.
Which is the trivially true output of the universal quantifier, ranging over the empty domain of discourse that is students who took a flight? The domain of discourse can never be the empty set, we must have "Something" to talk about, though we cannot say anything about it. Hence the oddity here. Simply stated: the no students that took the plain could afford it is true.
