Task: Question Answering
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 pharma students read about antiviral and antibacterial drugs. Manny read about antiviral drugs, while George read about bacteria and antibacterial drugs. 
Question: Which student didn't read about antiretroviral drugs?
Output (English): George.
