Final answer:
The correct form of the underlined verb in the sentence 'Her rolls always rise properly' is 'rise' with no change necessary because 'rise' does not require an object, which fits the context of the sentence.
Step-by-step explanation:
The question asks which form of the underlined verb is correct in the sentence 'Her rolls always rise properly.' When considering the correct form of a verb, it is essential to understand the meaning of the verb in the context of the sentence. The verb 'raise' means 'to lift' or 'to grow' and requires an object to be correct, as in 'She raised her hand.' In contrast, 'rise' means 'to get up' and does not take an object, similar to how 'the sun rises.'
Therefore, in the context of the sentence 'Her rolls always rise properly,' there is no object that is being acted upon by the rolls, they are doing the action on their own. Therefore, the correct answer is no change necessary because the word 'rise' is appropriately used for actions that do not require an object. Additional examples of correct verb usage are: 'Her watch and wallet were stolen' and 'The choir usually sings.'
