Problem: Hunter-gatherer:

Forest gardening was also being used as a food production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions.[citation needed] In the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior foreign species were selected and incorporated into the gardens.

What use did forest gardeners put to tree and vines to?
---
A: identified, protected and improved

Problem: Culture:

The modern term "culture" is based on a term used by the Ancient Roman orator Cicero in his Tusculanae Disputationes, where he wrote of a cultivation of the soul or "cultura animi", using an agricultural metaphor for the development of a philosophical soul, understood teleologically as the highest possible ideal for human development. Samuel Pufendorf took over this metaphor in a modern context, meaning something similar, but no longer assuming that philosophy was man's natural perfection. His use, and that of many writers after him "refers to all the ways in which human beings overcome their original barbarism, and through artifice, become fully human".

What term was used by the Ancient Roman Emperor Cicero in his Tusculanae Disputationes?
---
A: unanswerable

Problem: Brigham Young University:

A few special additions enhance the language-learning experience. For example, BYU's International Cinema, featuring films in several languages, is the largest and longest-running university-run foreign film program in the country. As already noted, BYU also offers an intensive foreign language living experience, the Foreign Language Student Residence. This is an on-campus apartment complex where students commit to speak only their chosen foreign language while in their apartments. Each apartment has at least one native speaker to ensure correct language usage.

As part of the Foreign Language Student Residence program, what do students commit to speak while in their apartments?
---
A: only their chosen foreign language

Problem: Data compression:

In lossy audio compression, methods of psychoacoustics are used to remove non-audible (or less audible) components of the audio signal. Compression of human speech is often performed with even more specialized techniques; speech coding, or voice coding, is sometimes distinguished as a separate discipline from audio compression. Different audio and speech compression standards are listed under audio coding formats. Voice compression is used in internet telephony, for example, audio compression is used for CD ripping and is decoded by the audio players.

What compression is usually performed with even more specialized techniques?
---
A:
human speech
