Link of the Day

Did you know that pi has the approximate value of 22/7? That's why some people celebrate Pi Day today (many people also celebrate Pi Day on March 14 - 3/14). Pi is the ratio of the circumference of a circle to its diameter. Because it's an irrational number (one that cannot be expressed as an exact ratio) it is impossible to calculate the exact value of pi. As of October 2011, pi has been calculated to 10 trillion digits (although you really only need to know the value to 3 digits for the SAT). You can read more about pi and Pi Day here.

7/22 Identifying Sentence Errors

The following sentence contains either a single error or no error at all. If the sentence contains an error, select the one underlined part that must be changed to make the sentence correct. If the sentence contains no error, select choice E.

When you are working an Improving Sentences question, read the question carefully and focus on the underlined portion. If you identify an error, make a prediction about how you could fix the error. The correct answer won't always match your prediction, but making a prediction will help you to identify the underlying grammar concept being tested.

The largest European type of newt grows to about seven inches, while the largest American type, the California newt, it grows to about six inches. No error

Take your time and read the question carefully until you find something that stands out. (A) doesn't have any error. The adjective is correctly used and clearly modifies one noun. (B) also doesn't have an error. The word "type" is correctly used (also, the word "of" is the correct preposition to use here). (C) is part of a clause and it is idiomatically correct. (D) should stand out to you.  It's awkward because there is an unnecessary pronoun that makes the comparison unclear. Without the pronoun "it", the comparison becomes "The largest European newt grows to about seven inches . . ." while the other "grows to be about six inches". Since you have identified an error, (E) cannot be the correct answer.

The correct Answer Choice is (D).
