    单选题
    The newest fiber-optic cables that carry telephone calls cross-country are made of glass so ______ that a piece 100 miles thick is clearer than a standard windowpane.
    A

    fragile

    B

    immaculate

    C

    iridescent

    D

    tangible

    E

    transparent


    正确答案： A
    解析：
    根据句法关系可以判断，后半句“a piece 100 miles thick is clearer than a standard windowpane”是对空格处词语的进一步解释，主要说明光纤电缆的材料的透明度比较高，因此选项中符合句意的只有E transparent（透明的；清澈的）；A fragile 脆弱的，易碎的；B immaculate 完美的，洁净的，无瑕疵的；C iridescent 彩虹色的，闪光的；D tangible 有形的，切实的，可触摸的。
