a. 1
b. 2
c. 3
d. 4
e. 5

ANSWER: 3
 
'Lest...should' is used to extend a warning and also suggest the consequences of not paying attention to that warning.
Warning +Lest+Person +Should +Consequence
Work hardlestyoushouldfail.
The use of this conjunction in any sentence conveys a negative sense. As such, 'no' or 'not' should not be used in that sentence.

Remove 'not'.

'Lest...should' already conveys a negative sense.

The correct sentence should be: Study hard lest you should fail.

** Lest is always followed by should, with a ‘not’ anywhere.
'should' here can not be replaced by 'would' or 'may'.


For e.g. Go through the notes again and again lest you would/may fail, is incorrect.
