问题     For centuries, oak were the wood of choice for European shipbuilders. However, toward the end of the eighteenth century, as British oak supplies grew scarce, shipbuilders there turned to teak and found in it an ideal substitute. Other woods expand and contract at different rates than oak, so repairs to oak ships done with those woods split or leak. Only teak matches oak’s expansion coefficient and stays watertight. It is unmatched in its resistance to rot and pests, and its oils even protect nails against corrosion. Moreover, it was one of two important tropical hardwoods (with Central American mahogany) that dried light enough to float downriver—the only way to transport timber in quantity from the inland jungles where it grew. [br] It can be inferred from the passage that an advantage of teak over mahogany is that teak is:
选项 A、more compatible with the materials in existing ships.
B、less susceptible to rot and pests
C、available in greater quantities in inland jungles
答案 A,B
解析 A项the materials in existing ships指的是橡木，根据第四句可知，只有柚木可以匹配橡木的膨胀系数，因此柚木当然比桃花心木更兼容于橡木。B项对应第五句，柚木在防腐蚀和虫害方面是无与伦比的，因此柚木当然比桃花心木更防腐蚀和虫害。C项无法得知，因为原文只说了柚木和桃花心木都能从内陆大量运出来，但是看不出谁更能被大量获得。
