Thank you for using the Jiskha Homework Help Forum.
6a would be present tense = I lay the book down now.
6b would be the past tense = I laid my book on the table, but now (check spelling there) I cannot find it.
You choose well!
9a = built = is the spelling, past tense
9b. have build = correct for Present Perfect.
You choose well again!
25a for many cities = check your spelling
25b = the spelling is correct.
Again you choose correctly!
Sra
thank you.
To determine if the given answers are correct, let's analyze each question and the rules for regular and irregular verbs, verb forms and tense, as well as vague pronouns.
6a. I lay my book on the table, but now I cannot find it.
6b. I laid my book on the table, but now I cannot find it.
In this case, we need to identify the correct verb form and tense. The verb "lay" is the past tense of the verb "lie" (which means to recline). So, the correct answer would be 6a, "I lay my book on the table, but now I cannot find it."
9a. The ancient Egyptians built pyramids as burial sites for their leaders.
9b. The ancient Egyptians have built pyramids as burial sites for their leaders.
To determine the correct verb form and tense, let's consider the context. Since the sentence is referring to something that happened in the past, the past tense "built" is appropriate. Therefore, the correct answer is 9a, "The ancient Egyptians built pyramids as burial sites for their leaders."
25a. Air pollution normally increases along with population growth. This increasing pollution is a big problem for many cities.
25b. Air pollution normally increases along with population growth. This is a big problem for many cities.
The issue in these sentences is with vague pronouns. In 25a, the pronoun "this" is referring to "increasing pollution," but the connection is not clear. In sentence 25b, the pronoun "this" is replaced with "Air pollution," which makes the meaning more precise. Hence, the correct answer is 25b, "Air pollution normally increases along with population growth. This is a big problem for many cities."
Therefore, your choices are correct:
6b is incorrect.
9a is correct.
25b is correct.
