第3题：
If the square root of t is a real number, is the square root of t positive?
(1) t＞0
(2) t2＞0
E 解析：This question is looking for a definite yes or no answer. Statement (1) is not sufficient since all it tells us is that t is a positive number. Unless the radical sign (
) is used, a positive number has two square roots, a positive root and a negative root. For example, if t is 4, then it has two square roots, 2 and -2. So we can eliminate A and D.With statement (2) alone, we don't get much more information; all it really tells us is that t is a positive number (it cannot be negative, since the square root of a negative number is a complex number, not a real number). So again, t could be 4, and its root could be either positive or negative. So we can eliminate B. Putting them both together doesn't tell us whether the square root of t is positive either, so our answer has to be E.

正确答案: 中文翻译为“戈尔迪之结”意思为棘手问题，难解问题。故事大概是一个叫戈尔迪得农夫赶着牛经过一个名叫弗利吉亚的国家，被当地人选为了国王，原因是有一先知预言戈尔迪就是他们未来的国王。戈尔迪为了感谢天神宙斯，以牛车祭示宙斯，他叫人用树皮做成了一根坚固无比的绳子，并亲自打了一个结，这就是戈尔迪之结。戈尔迪留下遗言，谁能解开此结，他将能统治整个小亚细亚。后来有一个人用剑斩断了结，他就是后来征服了整个小亚细亚的亚历山大大帝。
