Hi jainm1990,

you can click on the play button (Orange color) so that timer starts and then you click on the choice that you think is correct. After you click on a choice the correct choice is highlighted with Green. Your attempted questions are saved in workbook. You can go to your workbook and redo the questions using multiple options provided for sorting.

If you do not want to use the timer then just click on [Reveal] to see the answer.

Please ask if you have any specific question, i would try to help :)

Hi all,
I'm left with (C) and (E).Why we need "in which"?

You will realize it better if you understand how we derive "in which" construction.

The children play in the park.
Government ordered the renovation of the park.
We can combine both, by altering the construction of the initial sentence.

Government ordered the renovation of the park in which the children play.

So, now you realize how E works :

A mix of water and chemicals are blasted under-ground to create fissures in gas-bearing rocks in a drilling technique known as "hydraulic fracturing"
A drilling technique known as "hydraulic fracturing" has made XXXX.

So, this sentence works in the same way as above.

Where as, when we use "which", it acts as a subject, here as a performer of the action. The techniques itself does not blast .... but the blast take place as a part of "the" technique.

Cheers !! :-D

C changes the meaning of the original sentence.
According to C the technique ----->blasts a mix of water and chemicals(action is done )
Actual sentence describes the process IN the technique
Hope its clear

A)in which a mix of water and chemicals are blasted under-ground to create fissures in gas-bearing rocks, has made (a mix is singular so usage of 'are' is wrong)
B)in which a mix of water and chemicals is blasted under-ground to create fissures in gas-bearing rocks, making (Grilling technique is making extraction of gas totally awkward)
C)which blasts a mix of water and chemicals under-ground to create fissures in gas-bearing rocks, has made (hydraulic blasts a mix of water and chemicals)[color=#000000]
D) which is a mix of water and chemicals blasted under-ground to create fissures in gas-bearing rocks, [color=#ff0000]have
made (A drilling technique is singular)
E)in which a mix of water and chemicals is blasted under-ground to create fissures in gas-bearing rocks, has made (Correct)

Kudos please if you like my explanation!

A drilling technique known as X - singular - eliminate D

B lacks main verb -run-on sentence

The non-restrictive clause describes what happens in the technique so C is eliminated.

a mix of X and Y - "is" over "are"

Technique itself is not blasting anything.
"hydraulic fracturing" ----->which
But "in which" ------> in the technique "hydraulic fracturing"
Hope its clear
