Choice B is the best answer. Tom Peacock and his team created a model of the “Luzon’s Strait’s underwater topography” and determined that its “distinct double-ridge shape . . . [is] responsible for generating the underwater [internal] waves” (lines 53-55,"The...waves"). The author notes that this model describes only internal waves in the Luzon Strait but that the team’s findings may “help researchers understand how internal waves are generated in other places around the world” (lines 67-70,"Whereas...world"). The author’s claim suggests that while internal waves in the Luzon Strait are “some of the largest in the world” (line 25,"be...about") due to the region’s topography, internal waves occurring in other regions may be caused by some similar factors.
Choice A is incorrect because the author notes that the internal waves in the Luzon Strait are “some of the largest in the world” (line 25), which suggests that internal waves reach varying heights. Choices C and D are incorrect because they are not supported by the researchers’ findings.
