Final answer:
To correct the sentence, replace 'an' with 'a' resulting in 'Rita has a scooter which is red'. This follows the grammar rule that 'a' is used before words starting with a consonant sound, while 'an' is used for vowel sounds.
Step-by-step explanation:
The correct sentence should read, Rita has a scooter which is red. The error in the original sentence was a typo; 'an' should be replaced with 'a' because 'scooter' begins with a consonant sound. This is a standard grammar rule for indefinite articles - 'a' is used before words that start with a consonant sound, while 'an' is used before words that start with a vowel sound.
Looking at examples can often help us understand these kinds of grammatical rules better. For instance, in the sentence "Her truck, a red Chevy, was parked around the back of the house," we see the adjective 'red' is used correctly to describe the color of the noun 'truck'. Similarly, in the art context, such as Grace Hartigan's oil painting, colors play a significant role, and choosing the appropriate color description is crucial, as seen in "Essex and Hester (Red)". In this painting, Hartigan uses strong colors, including red, to draw attention to specific details.
Rita has a red scooter.
In this corrected sentence, we have changed 'an' to 'a' because 'scooter' begins with a consonant sound. We have also moved the adjective 'red' to describe the noun 'scooter' instead of being placed at the end of the sentence.
