plz help me out...

1: in pair of words, if one writes sentences of both the words but 1 right n ther wrong, will one get 1 mark for the right one or not...

2: in comprehension, did we use to write only the meaning of last question or some thing more as 8 words n 8 marks...

3: is it correct : neither of the 3 umbrellas will suit me.

thx
