Problem: Alexander Graham Bell:

In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk.[N 23] The tetrahedral wings were named Cygnet I, II and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 19071912. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site.

Problem: Buddhism:

Meditation was an aspect of the practice of the yogis in the centuries preceding the Buddha. The Buddha built upon the yogis' concern with introspection and developed their meditative techniques, but rejected their theories of liberation. In Buddhism, mindfulness and clear awareness are to be developed at all times; in pre-Buddhist yogic practices there is no such injunction. A yogi in the Brahmanical tradition is not to practice while defecating, for example, while a Buddhist monastic should do so.

In Buddhism, what must be developed at all times?
---
A: mindfulness and clear awareness

Problem: Exhibition game:

The Major League Baseball's preseason is also known as spring training. All MLB teams maintain a spring-training base in Arizona or Florida. The teams in Arizona make up the Cactus League, while the teams in Florida play in the Grapefruit League. Each team plays about 30 preseason games against other MLB teams. They may also play exhibitions against a local college team or a minor-league team from their farm system. Some days feature the team playing two games with two different rosters evenly divided up, which are known as "split-squad" games.

Which states do MLB teams do spring training in?
---
A: Arizona or Florida

Problem: Universal Studios:

Universal could seldom afford its own stable of stars, and often borrowed talent from other studios, or hired freelance actors. In addition to Stewart and Dietrich, Margaret Sullavan, and Bing Crosby were two of the major names that made a couple of pictures for Universal during this period. Some stars came from radio, including Edgar Bergen, W. C. Fields, and the comedy team of Abbott and Costello (Bud Abbott and Lou Costello). Abbott and Costello's military comedy Buck Privates (1941) gave the former burlesque comedians a national and international profile.

Who starred in the 1914 Buck Privates comedy?

A:
unanswerable
