Semiconductors, made from a silicon that makes modern computing possible are widely taken for granted in today’s world.

A)  NO CHANGE
B) made from silicon materials that make modern computing possible are
C) made from silicon materials that make modern computing possible, are
D) made from a silicon that makes modern computing possible, are[/vc_column_text][vc_text_separator title=”Day 6 Answer Explanation”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text](A) and (D) are incorrect because the phrase “made from a silicon” has the inappropriate article “a silicon” before silicon.  This is like saying ‘that plate is made from a gold.’

(A) and (B) are also incorrect because they do not have the comma after “possible” to clearly indicate the non-essential clause “made from silicon materials that makes modern computing possible”

(C) is correct because it appropriately removes the indefinite article “a,” it sets off the non-essential clause with commas, and has proper subject-verb agreement between “make” and “materials.”[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_text_separator title=”Key Grammar Fact To Learn” css=”.vc_custom_1486640939938{padding-top: 20px !important;}”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

Know the difference between essential and non-essential clauses.

An essential clause is a clause that is needed for the sentence to make sense.

“The man who ordered a dolphin last week is recognizing that his judgment needs a tune up.”

If we take the phrase out of the sentence above it leads to a nonsense sentence because we don’t know WHO “the man” refers to.

Grammar Rule: Essential clauses are not set off by commas.

An inessential clause is a clause that is not needed for the sentence to make sense, but is added because it contains important or relevant information.

“Mr. Jones, who ordered a dolphin last week, is recognizing that his judgment needs a tune up.

In this sentence, since we know the man is Mr. Jones, we can omit the underlined phrase and the sentence still makes sense.  Since it is a non-essential clause here, we must set it off with commas.

Grammar Rule: Non-essential clauses are set off with commas.
