Read the paragraph from “Stick to Real Microscopes.”
The piece I read also insisted that smartphone microscopes are better because they let users take video of what they observe. That is certainly good and useful. Being able to take video is valuable. And I do not intend to argue against that value. Rather, I will just say that one does not need a smartphone microscope to take video. I found several real microscopes that come with digital cameras and video recorders. They can record videos just as easily as a smartphone microscope, but they can do so at much higher magnification. Several cost around $300 (Gates). Again, the real microscope is the better scientific tool.
What is the author’s purpose in the paragraph?
A: To suggest that video capability is the most important feature for microscope users
B: To explain that real microscopes have video capability superior to smartphone microscopes
C: To compare the cost of microscopes with and without video and camera features
D: To argue that it is easier to take video with a real microscope than a smartphone microscope
