KEY NOTES:
- Comparison: "than any other" is always preferable to "than any". Why?
For example:
Wrong: Henry is taller than any people in his class --> you're comparing Henry with a group of people including himself.
Correct: Henry is taller than any other people in his class.

Today’s semi-conductor innovations allow chip makers to design silicon wafer chips more space efficient now than at any time since their inception.

(A) silicon wafer chips more space efficient now than at any time since their
Wrong.
"than any" is wrong. See explanation above.
"their" is wrong. "their" refers to current silicon wafer chips.

(B) silicon wafer chips that are more space efficient than they were at any time since their
Wrong.
"they" refers to current silicon wafer chips. That's a wrong comparison. You're comparing those chips with themselves? You need a new copy of "chips" --> "those" is correct.
"their" is wrong. See option A.

(C) silicon wafer chips that are more space efficient than those at any other time since
Correct. Good comparison.

(D) more space efficient silicon wafer chips than those at any other time since their
Wrong.
"their" refers to what? "silicon wafer chips" or "those".

(E) more space efficient silicon wafer chips now than at any time since
Wrong.
"now" is redundant. See the non-underlined "Today......"
"than any time" is wrong. See explanation above.

Hope it helps.

Today’s semi-conductor innovations allow chip makers to design silicon wafer chips more space efficient now than at any time since their inception.

(A)
silicon wafer chips more space efficient now than at any time since their ---- their ambiguous --X

(B)
silicon wafer chips that are more space efficient than they were at any time since their -- Same as A

(C)
silicon wafer chips that are more space efficient than those at any other time since ---Best choice. That- is used correctly

(D)
more space efficient silicon wafer chips than those at any other time since their -- Same as A

(E)
more space efficient silicon wafer chips now than at any time since -- now

Hi AbhiB,
I'm a little confused at the phrase "since inception"--is that correct?

I do see how their is ambiguous in referencing either the innovations, chip makers or the chip themselves right?

Hi intheend14,

There's nothing wrong with 'since inception'. If you read the whole sentence with option 'C', then your ear will guide you.

Yes, you are right about ambiguity.

Thanks !

Hello,

Can you please explain why the use of 'their' is incorrect? I do not understand how it refers to CURRENT silicon wafer chips??

Thanks
