Astronomy quiz

lola777 — 04.02.2011 Что-то я начинаю сомневаться, что я могу справиться с такой загрузкой - работать и учиться фулл-тайм. У меня уже мозг не варит от недосыпа, теперь пишу неправильно многие слова, детали вообще перестала замечать и даже стала иногда вместо женских в мужские туалеты заходить(зрительный рецепторы тоже плохо работать стали ;).

Зато у нас каждую неделю по астрономии тест и я наконец-то 12 из 12 набрала. Если кто хочет понять, что вы ниче не знаете проверить свои знания - можете сделать это под катом. Время дается час, но можно пользоваться литературой. Я потом скажу, сколько вы набрали правильных ответов.
