Understanding the Sentence Structure

The sentence describes a contrast between Jane's feelings about her dance performance and her teammates' performance. The structure "felt ______, than her teammates" clearly indicates the need for a comparative adjective in the first blank. The second blank describes the manner in which the teammates moved, modifying the noun 'grace'.

Analyzing the First Blank: Comparative Adjective

Jane practiced for weeks but still felt ______ compared to her teammates. Because the sentence uses "than her teammates", we need a word that compares Jane's state to her teammates'.

• Clumsy is a positive adjective. Its comparative form is clumsier.
• Clumsiest is the superlative form, used when comparing three or more items. It's not appropriate here since we are directly comparing Jane to her teammates.

Therefore, 'clumsier' is the correct comparative adjective to express that Jane felt more awkward than her teammates.

Analyzing the Second Blank: Describing Grace

The teammates seemed to move with ______ grace. We need a word to describe the type of grace they exhibited.

• Effortless is an adjective meaning 'achieved without apparent effort'. This fits perfectly to describe graceful movement that looks natural and easy.
• More effortless is also grammatically possible, implying an even greater degree of effortlessness. However, 'effortless' itself is sufficient and often preferred in such constructions for conciseness unless a specific emphasis on *more* effortlessness is intended. Given the contrast, 'effortless' directly describes the quality.

Evaluating the Options

Let's look at how the options fit:

• Option 1: clumsy; more effortless
  Incorrect because 'clumsy' is not comparative.
• Option 2: clumsier; effortless
  Correct. 'Clumsier' is the comparative adjective needed for the first blank. 'Effortless' is the appropriate adjective for the second blank, describing the teammates' grace.
• Option 3: clumsy; effortless
  Incorrect because 'clumsy' is not comparative.
• Option 4: clumsiest; more effortless
  Incorrect because 'clumsiest' is a superlative, not a comparative.

Final Conclusion

The most appropriate choice is Option 2, which uses the comparative adjective 'clumsier' and the descriptive adjective 'effortless'. This correctly conveys that Jane felt more awkward than her teammates, who moved with a grace that seemed to require no effort.
