While researching a topic, a student has taken the following notes:
<ul> <li>Stalactites are mineral formations that hang from cave ceilings.</li> <li>They form as mineral-rich water drips from above.</li> <li>Stalagmites grow up from cave floors.</li> <li>They form from the same dripping water that creates stalactites.</li> <li>Both can fuse into a column over millennia.</li> </ul> The student wants to contrast where stalactites and stalagmites form. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- A
Mineral-rich water drips into caves.
- B
Stalactites and stalagmites form from the same mineral-rich water.
- Ccheck_circle
Stalactites hang from cave ceilings, while stalagmites grow up from cave floors.
- D
Both can fuse into a column over millennia.
Explanation
The goal is contrasting location of formation. Choice B states ceiling vs. floor. A and C state similarities; D is too general.
