###Implement a question answering system using Gradio's lower-level API. The system features two input fields: the first for the context and the second for the user's question. The system then outputs the model's response

Cryptocurrency is a digital currency secured by cryptography, existing on decentralized networks using blockchain technology.
It's not issued by any central authority, making it theoretically immune to government interference.
Blockchain is a connected set of blocks of information on an online ledger, containing verified transactions.
Cryptocurrencies like Ethereum's ether and Ripple's XRP serve specific purposes on their blockchains.
The legal status of cryptocurrencies varies by country; in the US, they're considered a form of money.
Despite risks like scams and volatility, cryptocurrencies have a market capitalization of about $1.2 trillion.
They offer advantages such as easier fund transfers but also have disadvantages like criminal uses and volatile prices.
