Marina Protocol rewards users for engaging with educational Web3 content through its daily quiz feature. As of May 15, 2025, users can earn crypto by answering a simple multiple-choice question correctly, helping them strengthen their knowledge of blockchain and related technologies. The app currently serves over 3 million users and offers an accessible way to earn passive crypto income while learning.
Today’s Quiz Answer – May 15, 2025
Question: Which of the following best describes a model-based agent?
Correct Answer: B) Maintains internal state for decision-making
A model-based agent refers to a system that doesn’t just react based on current input. Instead, it uses an internal model of the world—storing and using past information—to make smarter decisions. This type of agent is often found in artificial intelligence and robotics, where decisions depend on more than just immediate data.

If you’re using Marina Protocol for the first time or returning for your daily rewards, here’s how it works:

Other Ways to Earn on Marina Protocol
While the quiz is a quick way to earn, the platform offers additional features that allow users to grow their crypto holdings steadily:
- Auto-Mining: This feature lets users earn pSURF coins daily with just one tap. Hit the mining button once every 24 hours. Watching an ad afterward boosts your reward, with a maximum of 60 pSURF per day.
- Daily Tickets: Watch up to 10 ads daily to collect 10 tickets. Each ticket earns 0.002 pBAY tokens. After completing all the ads, head over to the pBAY section and open your ticket box to claim your rewards.
- Referral Program: By inviting new users to the app using your unique referral link, you can earn bonus rewards. Every successful referral increases your crypto balance while helping Marina Protocol grow its community.
If you’re aiming to consistently get quiz answers right, spend a few minutes reviewing basic Web3 and blockchain concepts. Most questions focus on these topics or the core features of the Marina platform itself. You can also join the official Marina Protocol groups on Telegram or Discord—community members often share the latest answers and updates.
Once you answer and claim your reward, check your wallet balance in the app. The accumulated pSURF tokens can be used or exchanged within the ecosystem later.
