Correct Answer: A

Rationale: The correct answer is A: Dejected. After becoming INVALID, one is likely to feel dejected, meaning sad and disheartened due to feeling invalidated or rejected. It is a common emotional response to a situation where one's worth or validity is questioned or denied. Option B, shamefully fearful, does not directly relate to the emotional state associated with being an invalid. Option C, injured, does not capture the emotional aspect but rather focuses on the physical condition. Option D, symbiotic, refers to a mutually beneficial relationship between two different organisms and is not relevant to the emotional state of an individual after becoming an invalid.

Correct Answer: C

Correct Answer: A

Rationale: A prefix is the correct answer. A prefix is a word part attached at the beginning of a word to modify its root word, changing the definition or grammatical function of the word. Examples of prefixes include "un-" in "unhappy," "re-" in "redo," and "pre-" in "preview." Choice B, "Affix," is incorrect because while a prefix is a type of affix, not all affixes are prefixes. Choice C, "Suffix," is incorrect as a suffix is a word part added at the end of a word to change its meaning. Choice D, "Vocab," is incorrect as it refers to vocabulary or words related to a particular subject rather than a word part placed before a word.
