From your explanation it seems . "it" refers to cost . I am still not getting what "they" refer to . Is it travellers or is it Vacations ? :( Explanation from Bob , "It" here has no antecedent . It's not really a pronoun . It's the subject of the impersonal verb "seemed" .

Whats wrong with A, B, C ? Are we choosing E to maintain parallelism ?

For many travelers, charter vacations often turn out to cost considerably more than they originally seemed. (A) they originally seemed (B) they originally seem to © they seemingly would cost originally (D) it seemed originally (E) it originally seemed they would This has been discussed many times before , but i could not get clear answers . What does 'It' refer to and what does 'they' refer to here ? OA

A should be the answer .

Using 'along with' would break parallelism . why cant we have plural after 'along with' ?

Thank you for examples Devp . In first example , do we need a comma before 'which' ? The first example is 'nonrestrictive' clause whereas the second is 'restrictive' . Is that correct ?

one doubt here , coming across this for first time 'restrictive clause' I could understand that 'that' introduces restrictive clause Can which never introduce a restrictive clause . Can someone give some examples of restrictive clause ?

@ effective factor , Can you please elaborate more on why 'by twice' is improper . Thanks

So we reject D on the grounds of run-on ?

Good one !

IMO E . For stmt 2 , a can be 2 or -2 .

Can somebdy throw mre light on Standard dev ?

ah , i went for D Missed to put negative values ... tricky !

Had it been given that the probability of a bird having avian flu is 1/2 ( or 1/3 or whatever ) , what would be the answer ?

one is 13 and other is 41 .... E it is !

IMO Each alone should be sufficient !

If you take a = -5 and b = 1 , LHS = -1/6 RHS = 6 LHS

60/(x-5) - 60/x = 2 where x is the number of members initially !

both together are sufficient ..... nice question !

Nice explanation 12rk34 , I think the cux is to get these combinations (1,5), (2,4), (3,3), (4,2), (5,1) only one will satisfy . Good question !

|a - b| just gives us the difference and does not tell us which one is greater or smaller .

D it is !

D it is !

B it is !

I go for A too
