SAT #17 Reading (Question 31)

Question

Which statement about reflectance patterns in Monotropsis odorata is best supported by the data presented in figure 1?

Answer 1

Answer Choice D is the correct answer because figure 1 measures the reflectance and wavelength for four features of Monotropsis odorata, and the line measuring “bract” and that which measures the “reproductive stem” diverge significantly, most closely matching Answer Choice D which says that “the bract reflectance pattern differs substantially from the reproductive stem reflectance pattern.” Answer Choice A is incorrect because the flower petal and bract reflectance patterns do not follow one another. Answer Choice B is incorrect because the trend where the leaf litter line decreases while the flower petal line increases isn’t represented by the graph, and in fact all four lines increase together. Answer Choice C is incorrect because the line measuring the stem reflectance pattern differs significantly from that measuring the leaf litter reflectance pattern.
