1 is wrong; 2 and 3 are right.

To determine the correct answer to each question, we can break down the sentences and analyze the context in which the words are used.

1. In the sentence, "My mind and body were so (oppressed, heeded) by the stifling heat that afternoon that I couldn't do anything at all," the word "oppressed" means heavily burdened or overwhelmed. It makes sense in this context because the stifling heat is negatively affecting both the mind and body. Therefore, the correct answer is "oppressed."

2. In the sentence, "Education and compassion are the only weapons by which we will (heed, vanquish) prejudice and superstition once and for all," the word "vanquish" means to defeat or conquer. In this context, education and compassion are presented as tools to overcome or eliminate prejudice and superstition. Therefore, the correct answer is "vanquish."

3. In the sentence, "The man's pathetically (wan, elongated) personality is matched only by the hopelessly bland and lifeless statements that issue from his mouth," the word "wan" means pale or lacking vitality. It is used to describe the man's personality as lacking energy or vibrancy. Therefore, the correct answer is "wan."
