小知识
Rudimentary means basic, or at a very early stage. The test should be easy: it requires only a rudimentary understanding of the materials.
The word rude means simple or offensive — and people with only rudimentary understanding of good manners might not know how that belching is rude. If you remember that the word rude is the foundation of rudimentary, you'll have a rudimentary understanding of the word.
