Final answer:
The Waze GPS navigation app likely receives millions of user reports on routes and road conditions each month, due to its large global user base and the real-time nature of the data it provides.
Step-by-step explanation:
The student asked about the volume of crowdsourced reports on routes and road conditions that Waze receives each month. Waze, being a popular community-driven GPS navigation app, relies on user reports to provide real-time travel data and road conditions. While the exact number of reports can fluctuate, the correct answer is likely B. Millions. Waze has a global user base, and given the app's popularity, it is reasonable to assume that it receives millions of reports from its users every month. These reports help in providing accurate and up-to-date traffic information, road closures, and alerts on hazards.
