Here is a question about this article: Over 50% of undergraduate students live on campus. Most of the residence halls on campus are located on the South 40, named because of its adjacent location on the south side of the Danforth Campus and its size of 40 acres (160,000 m2). It is the location of all the freshman buildings as well as several upperclassman buildings, which are set up in the traditional residential college system. All of the residential halls are co-ed. The South 40 is organized as a pedestrian-friendly environment wherein residences surround a central recreational lawn known as the Swamp. Bear's Den (the largest dining hall on campus), the Habif Health and Wellness Center (Student Health Services), the Residential Life Office, University Police Headquarters, various student-owned businesses (e.g. the laundry service, Wash U Wash), and the baseball, softball, and intramural fields are also located on the South 40.
What is the answer to this question: What is the gender make-up of the residence halls at Washington University?

Question: Read this and answer the question

Airborne Interception radar (AI) was unreliable. The heavy fighting in the Battle of Britain had eaten up most of Fighter Command's resources, so there was little investment in night fighting. Bombers were flown with airborne search lights out of desperation[citation needed], but to little avail. Of greater potential was the GL (Gunlaying) radar and searchlights with fighter direction from RAF fighter control rooms to begin a GCI system (Ground Control-led Interception) under Group-level control (No. 10 Group RAF, No. 11 Group RAF and No. 12 Group RAF).

What was considered unreliable?
Answer: Airborne Interception radar

Problem: In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
What act needed provisions?
The answer is the following: FD&C

Input: Article: In Buddhist practice, it is said that while samatha meditation can calm the mind, only vipassana meditation can reveal how the mind was disturbed to start with, which is what leads to insight knowledge (jnana; Pali nana) and understanding (prajna Pali panna), and thus can lead to nirvana (Pali nibbana). When one is in jhana, all defilements are suppressed temporarily. Only understanding (prajna or vipassana) eradicates the defilements completely. Jhanas are also states that Arahants abide in order to rest.

Now answer this question: What is the term for understanding?

Output:
prajna
