未分类题Task 2Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.If you ever have a chance to go to Finland(芬兰), you'll probably be surprised to find how 'foolish' the Finnish people are. You can go anywhere for one dollar, tell the driver to drop you at any place, say that you have some business to attend to, and then stalk off without paying your fare or give any demonstration of your good faith. And the driver will not show the least sign of anxiety. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals, and the most they would do to show their good faith is to wave their registration card to the waiter.

With so many loopholes(漏洞) in everyday life, surely Finland must be heaven to those who love to take 'petty advantages'. As the Finns always act on good faith and always adopt an attitude of 'which is which' and 'what is what' in everything they do, so to live in such a society has turned everyone into real gentleman.The word 'foolish' in the first paragraph probably means ______.A．friendlyB．crazyC．stupidD．funny
