Which platform provides practice exercises and instructional videos across subjects?

• A. Khanmigo
• B. Khan Academy
• C. Tinker v. Des Moines
• D. Afroyim v. Rusk

Answer: (B)

The main idea is identifying a platform that combines practice exercises with instructional videos across many subjects. Khan Academy fits this description because it offers a vast library of free instructional videos and thousands of practice problems spanning math, science, economics, humanities, and more. It’s designed for self-paced learning, providing videos to explain concepts and interactive exercises to apply them, with progress tracking to see how you’re improving over time. The other options aren’t educational platforms with that broad, across-subject combination: two are Supreme Court cases, and the remaining option is a tutoring feature within Khan Academy rather than the general platform itself.
