Willow trees typically thrive in moist environments like floodplains and river banks. In this climate, these trees grow very rapidly. (1) ______. The wildlife eats from its leaves. In ancient texts from Assyria, Sumer, and Egypt, the willow tree’s bark and leaves are mentioned as a remedy for fever and aches. Salicin, an active compound found in the bark of the willow tree, is a component of numerous medicines. (2) ______. The common osier’s twigs are grown for basket making, while other willow trees’ light, dent-resistant wood is used to make artificial limbs, wooden shoes, cricket bats, brooms, cradles, chairs, dolls, flutes, poles, toys, tool handles, wands, and whistles.

A. Aspirin is a salicylic acid derivative created by synthesis of willow bark derivatives.
B. In many ways, the willow tree is very helpful.
C. The arctic and alpine species of some willows are creeping or low-growing shrubs.

  • A.BA
  • B.AB
  • C.CB
  • D.AC

Answer: A

The answer is B for gap 1 and A for gap 2. After saying that willows grow very rapidly, the passage needs a general remark that links to the next sentence on wildlife eating the leaves, which is B, the willow tree is very helpful in many ways.

The gap after salicin being found in the bark and used in medicines needs the sentence about aspirin, which is made from a salicylic acid derivative, so it is A. Sentence C on creeping arctic shrubs is the extra sentence, since it does not fit either place. So the order is B then A.
