Hard SC problem

by \'manpreet singh » Mon Aug 26, 2013 1:10 am
The defective thermometers will sometimes fail to register a fever when it is present and indicate that there is one when it is not.

a a fever when it is present and indicate that there is one
b a fever when it is present and indicate that one is present
c when a fever is present and indicate that there is one
d when a fever is present and indicates its presence
e the presence of a fever when it is there and indicates its presence

Ans b

I feel that A ends abruptly.Overall i feel present or presence should be mentioned twice to maointain parallelism.

E, though it was a option for me while considering, it is too wordy

D and C Somehow "when a fever is present" feels absurd usage on the ears

B seems a good choice"that one" implies fever here.

Good question Manpreet!
You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!

Hi vinay,

Thanks for appreciating, though i got tricky by this short SC question myself.

We can eliminate D and E on the grounds of subject verb agreement also as subject is thermometers and and it needs a plural verb,so indicates is wrong.

Hi,

To add some additional perspective, there is another way to eliminate C, D and E:

A thermometer will register an outcome (a number, a temperature, a fever, etc.). It can't register a "time" (answers C and D start with the word "when", which implies a time) nor can it register a presence (E starts with "the presence").

Between A and B, parallelism is required to choose the correct answer.

Hi vinay1983,

The parallel phrases in this SC should be:

"register a fever when it is present" and
"indicate that one is present..."
