Task: Question Generation
Input (English): Background Paragraph: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. 
Story: Two friends had different diseases. Nigel was more prone to viral infections, so one day he got infected with the HIV virus. Manny had contracted some sort of bacterial infection.
Output (English): Which friend received more interferon?
