    ],
    "answer": "enduring",
    "explanation": "The correct answer is <i>enduring.</i> \n\n<i>Ephemeral</i> means lasting for a very short time; something that is fleeting or transitory. On the other hand, <i>enduring</i> means lasting over a long period or permanent, which is the direct opposite of <i>ephemeral.</i> \n\n<i>Fleeting,</i> <i>transient,</i> and <i>momentary</i> are synonyms of <i>ephemeral,</i> all describing things that are short-lived or temporary.\n\nWhile the beauty of a cherry blossom is <i>ephemeral</i>, a diamond's brilliance is <i>enduring</i>."

    "answer": "obscure",
    "explanation": "The correct answer is <i>obscure.</i> \n\n<i>Elucidate</i> means to make something clear or to explain thoroughly. Conversely, <i>obscure</i> means to make something difficult to understand or conceal, which is the antonym of <i>elucidate.</i> \n\n<i>Clarify,</i> <i>explain,</i> and <i>illuminate</i> are synonyms of <i>elucidate,</i> all involving making information clear and understandable.\n\nThe teacher aimed to <i>elucidate</i> the complex theory, not to <i>obscure</i> it further."

    "answer": "anomaly",
    "explanation": "The correct answer is <i>anomaly.</i> \n\n<i>Paradigm</i> refers to a typical example or pattern of something; a model that is standard or widely accepted. In contrast, an <i>anomaly</i> is something that deviates from the norm or expectations, which is the antonym of <i>paradigm.</i> \n\n<i>Model,</i> <i>example,</i> and <i>standard</i> are synonyms of <i>paradigm,</i> all representing typical or expected patterns.\n\nWhile the scientist's findings supported the existing <i>paradigm</i>, one unexpected result proved to be an <i>anomaly</i>."

    ],
    "answer": "overt",
    "explanation": "The correct answer is <i>overt.</i> \n\n<i>Surreptitious</i> means kept secret, especially because it would not be approved of; done stealthily. Conversely, <i>overt</i> means done or shown openly, not hidden, which is the antonym of <i>surreptitious.</i> \n\n<i>Clandestine,</i> <i>secret,</i> and <i>covert</i> are synonyms of <i>surreptitious,</i> all relating to hidden or concealed actions.\n\nTheir <i>surreptitious</i> meetings were eventually replaced by <i>overt</i> collaborations once the project was publicly announced."

    "explanation": "The correct answer is <i>worsen.</i> \n\n<i>Ameliorate</i> means to make something better or improve it. In contrast, <i>worsen</i> means to make something worse or deteriorate, which is the antonym of <i>ameliorate.</i> \n\n<i>Improve,</i> <i>enhance,</i> and <i>alleviate</i> are synonyms of <i>ameliorate,</i> all indicating positive changes or improvements.\n\nEfforts to <i>ameliorate</i> the situation were unsuccessful, and the conditions continued to <i>worsen</i>."
