Question

she has written, “cell phones shouldnt be allowed in an educational setting because research shows they have a negative affect on children.”
how can you help her rewrite this sentence correctly?
○ cell phone shouldnt be allowed in an educational setting because research shows they have a negative affect on children.
○ cell phones shouldnt be allowed in an educational setting because research shows they have a negative effect on childrens.
○ cell phones shouldnt be allowed in an educational setting because research show they have a negative affect on children.
○ cell phones shouldnt be allowed in an educational setting because research shows they have a negative effect on children.

Explanation:

1. Analyze the first option: "Cell phone" is singular, but "they" later is plural, so subject - verb (pronoun) agreement is wrong. Also, "affect" is a verb, but here we need a noun, so it should be "effect".
2. Analyze the second option: "childrens" is a misspelling. The plural of "child" is "children".
3. Analyze the third option: "research" is a singular noun, so the verb should be "shows" (not "show"). Also, "affect" is incorrect; it should be "effect".
4. Analyze the fourth option: "Cell phones" (plural, agrees with "they"), "shows" (agrees with singular "research"), "effect" (correct noun form), and "children" (correct plural form) are all used properly.

Answer:

D. Cell phones shouldn't be allowed in an educational setting because research shows they have a negative effect on children. (Here we assume the options are labeled A, B, C, D in order. If the original options have different labels, adjust accordingly. But based on the given options, the last one is correct.)
