Which of the following is a simple sentence?

The prefix "ir-" means "not," and the suffix "-ible" means "able to be." Combined, "irresistible" means "not able to be resisted." This explains the meaning of the word accurately.

Editing is the final step that focuses on refining grammar, punctuation, clarity, and overall polish. Drafting and researching happen earlier, while interviewing is usually a research method.

"On the other hand" signals contrast and helps connect ideas smoothly. The other options are adverbs describing manner or time, not transitions.

Option B correctly uses the possessive form with an apostrophe in "Sally's" and includes proper punctuation and grammar. The other choices either lack apostrophes or use them incorrectly, or they end improperly without punctuation.

Personalized feedback typically addresses behavior or learning qualities, such as "accepts redirection well." The other options state facts about Matthew rather than provide constructive or behavioral feedback, which is more helpful in a teaching context.

All pairs are homophones—they sound alike but have different meanings and spellings.

Option B uses the apostrophe correctly to show possession—"Our home's roof" indicates that the roof belongs to the home. The other options misuse apostrophes either by adding them unnecessarily or placing them incorrectly.

The prefix "il-" means "not," so "illiterate" means unable to read or write. Other options have different meanings: alliteration is a literary device, obliterate means to destroy, and preliterate refers to before literacy.

Passive voice occurs when the subject receives the action, as in "The exams were graded." The other sentences are active voice.

The prefix "circum-" means "around," so adding it to "vent" (meaning to come or go) forms a word meaning to go around. Other prefixes don't convey "around."
