First, let's restate the question and the answer choices to make sure we’re evaluating the right items. The sentence to complete is: The ___________math problem was so difficult that many students had to go to visit the teacher during FLEX to recieve extra help. The students who asked questions did better on the test! Complexly, complix, complexity, complex, cumplex.
Option 1: complexly. This word is an adverb form (meaning in a complex manner). It does not correctly modify the noun 'math problem,' so it would be grammatically incorrect here. We need an adjective to describe the noun problem, not an adverb.
Option 2: complix. This is a nonstandard, invented spelling that does not appear in standard English dictionaries. It would be inappropriate in formal writing and would not convey the intended meaning of a difficult math problem.
Option 3: complexity. This is a noun meaning the state or quality of being complex. It cannot directly modify the noun 'math problem' in this slot without awkward wording (e.g., 'the complexity math problem' would be ungrammatical). In proper usage, we would need a phrase like 'a problem of complexity' rather than 'the complexity math problem.'
Option 4: complex. This is an adjective meaning 'complicated' or 'not easy to solve.' It correctly modifies the noun 'math problem' to describe its difficulty, which fits the context of students needing extra help and later performing better after asking questions.
Option 5: cumplex. Like complix, this appears to be a nonstandard or invented spelling and would not be appropriate or understandable in standard English.
A key consideration is grammatical fit: we want an adjective directly describing the noun 'math problem.' Among the choices, 'complex' is the only standard adjective that properly fills the blank and yields a natural, correct sentence: 'The complex math problem was so difficult...'
Additionally, the surrounding sentence supports this choice: students who asked questions did better on the test, which aligns with a scenario where a challenging (complex) problem prompts seeking help and improved understanding. The other options fail due to incorrect part of speech, nonstandard spelling, or awkward phrasing that disrupts the sentence structure.
So, Option 4 ('complex') is the grammatically and semantically appropriate completion of the sentence, while Options 1, 2, 3, and 5 either mislabel the word class, use nonstandard spellings, or create ungrammatical phrasing that breaks the intended meaning.
