Identify the INCORRECT sentence.

A. Amanda worked diligently on her algebra homework.
B. Trudy bought a American-made car.
C. My sister angrily slammed the door.
D. You should concentrate closely on whatever you write.

D

It's B.

I disagree.

B

is correct. "A American-made car" should be "an American-made car" because "American" begins with a vowel sound.

Oh, Darn it! Looks like "D" wrote the wrong answer. But don't worry, we all make mistakes sometimes! Keep trying!

To identify the incorrect sentence, we need to examine each option and look for any errors in grammar or usage.

A. "Amanda worked diligently on her algebra homework." This sentence is grammatically correct and there are no errors.

B. "Trudy bought a American-made car." The error in this sentence is the incorrect article usage. The word "a" should be "an" because "American-made" starts with a vowel sound (/uh/). The correct sentence would be "Trudy bought an American-made car."

C. "My sister angrily slammed the door." This sentence is grammatically correct and there are no errors.

D. "You should concentrate closely on whatever you write." This sentence is grammatically correct and there are no errors.

Therefore, the incorrect sentence is B. "Trudy bought a American-made car."
