Central Board Of Secondary Education [CBSE] — Errors in answer key of english in term 1 exam

I don't know why CBSE is making errors in the answer key of English. i think it is because there are more than one possible answers to the question given or due to wrong interpretation of CBSE answer key maker in term 1 exam of English. it is not the case in English exam only but also in S.St exam too. and in case of science exam, of the set i got, there were some wrong option given in the official answer key. after observing all these things i request CBSE to do the justice to each and every student by giving bonus marks.
in the attachment, i have given some question asked in set-4 question paper series 002/1/4. please have a look on them and act positively. because CBSE is like our(students) judiciary who can only give us our desired justice.
