Lecture3 关于海洋植物学的。
5. What can be inferred about the process that prevents Spartinas from breaking in violent storms?
A. It is the same process that helps them survive being immersed in saltwater.
B. The process is also responsible for causing their air tubes to form.
C. The process sometimes damages their rhizomes. D. Many other pants have developed a similar process.
正选是A。我选了D。我明白A的解释是在第一种adaption里也提到，用的都是reverse osmosis。
但是也有提到 interlock with other plants，为什么不能理解成其他植物也有这种机制呢？
