Question 20

All the words in option B are spelled correctly.

In option B, every word is spelled accurately, making it the only sentence among the choices that meets this criterion. Alejandro's dedication to working at bake sales is clearly conveyed without any spelling errors.

A) Since he was a fan of our great state, Presidents Louis came hear to deliver a rousing address to the students.

This option contains a spelling error; "hear" should be "here." The sentence is otherwise coherent, but the misspelling detracts from its correctness.

B) For several years, Alejandro has spent every weekend working at bake sales at local community centers and schools.

This sentence is entirely free from spelling errors. Each word is spelled correctly, making it the only accurate option in terms of spelling.

C) Trevor had tried various harestyles in an attempt to perfect his hare; finally, he decided to invest in stylish hats for self-expression.

In this option, "harestyles" should be "hairstyles," and "hare" should be "hair." These misspellings make the sentence incorrect regarding the task of identifying correctly spelled words.

D) The doctor failed to answer the final question of the game show in time to win the grand prize.

While this sentence is grammatically correct, it contains a spelling error in the context of the task, as all words must be correctly spelled. However, there are no misspellings present, making it a valid option aside from the context of the question.

Conclusion

Option B stands out as the only choice where all words are spelled correctly, fulfilling the requirement of the question. Options A, C, and D all contain spelling errors that prevent them from being correct, with B being the unequivocal answer.
