Errors in Paragraph 2 in Swimming Strokes by Lee Carroll are and brush for subject-verb agreement, right-arm pull, left-arm pull, right-arm pull and breathe on the left side for parallelism, and your for pronoun-antecedent agreement. Are these correct?

Which "your"? There are umpteen instances of "your" in that paragraph.

I've made bold the two subj-verb agr errors I think you mean (since Sra gave them to you earlier). And I think you're right about the parallelism error.

Paragraph 2: When most people think of swimming, they think of the crawl stroke. It involves flutter kicking with your legs as you pull yourself through the water with your arms while alternating your breathing from side to side. The most important part of the crawl stroke is the pull, so strength in the arms are important. The motion of the arms are hand-over-hand. To do the pull, start with the left arm bent at the elbow with the hand pointed down to your hip while the right hand is stretched out in front of you. Pull the hand down through the water until it brush your right thigh. At the same time, bring your right elbow up and reach out in front of you with your right hand. Then repeat the pattern. To me, the hardest part of the crawl stroke is getting the rhythm of your breathing down. A typical pattern is right-arm pull, left-arm pull, right-arm pull and breathe on the left side; followed by left-arm pull, right-arm pull, left-arm pull while breathing on the right side.

To determine whether the errors in Paragraph 2 of "Swimming Strokes" by Lee Carroll are indeed errors and to identify the appropriate corrections, we need to analyze the specific issues mentioned.

1. "and brush" for subject-verb agreement: To confirm whether there is a subject-verb disagreement, we need to identify the subject and the corresponding verb in the sentence. However, the sentence you provided does not contain a verb, so we cannot determine if there is an agreement issue here. It is possible that this is an incomplete sentence or that there is missing context.

2. "right-arm pull, left-arm pull, right-arm pull, and breathe on the left side" for parallelism: Parallelism ensures that items listed in a sentence have a similar grammatical structure. In the given sentence, the repetition of "right-arm pull" may indicate a lack of parallelism. One possible correction for parallelism could be: "right-arm pull, left-arm pull, left-arm pull, and breathing on the left side."

3. "your" for pronoun-antecedent agreement: Pronoun-antecedent agreement means that a pronoun should agree in number and gender with its antecedent (the noun it refers to). Without the full sentence, it's challenging to determine the antecedent for "your." However, it should be noted that "your" is a second-person pronoun and generally refers to the person being addressed. Hence, if the sentence addresses the second person, "your" would be appropriate.

In summary, based on the information provided, the potential errors mentioned are the lack of parallelism regarding the repetition of "right-arm pull" and the need for clarification regarding the subject-verb agreement. However, without further context or the full sentence, a comprehensive assessment is difficult.
