Problem: Energy:

Sunlight may be stored as gravitational potential energy after it strikes the Earth, as (for example) water evaporates from oceans and is deposited upon mountains (where, after being released at a hydroelectric dam, it can be used to drive turbines or generators to produce electricity). Sunlight also drives many weather phenomena, save those generated by volcanic events. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, give up some of their thermal energy suddenly to power a few days of violent air movement.

When may sunlight be stored as gravitational kinetic energy?

A: unanswerable


Problem: Printed circuit board:

In boundary scan testing, test circuits integrated into various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted correctly. Boundary scan testing requires that all the ICs to be tested use a standard test configuration procedure, the most common one being the Joint Test Action Group (JTAG) standard. The JTAG test architecture provides a means to test interconnects between integrated circuits on a board without using physical test probes. JTAG tool vendors provide various types of stimulus and sophisticated algorithms, not only to detect the failing nets, but also to isolate the faults to specific nets, devices, and pins.

What component of the printed circuit board is appraised with boundary scan testing?
---
A: ICs


Problem: Federalism:

China is the largest unitary state in the world by both population and land area. Although China has had long periods of central rule for centuries, it is often argued that the unitary structure of the Chinese government is far too unwieldy to effectively and equitably manage the country's affairs. On the other hand, Chinese nationalists are suspicious of decentralization as a form of secessionism and a backdoor for national disunity; still others argue that the degree of autonomy given to provincial-level officials in the People's Republic of China amounts to a de facto federalism.

What are Chinese nationalist in favor of?
---
A: unanswerable


Problem: Tucson, Arizona:

Catalina Highway stretches 25 miles (40 km) and the entire mountain range is one of Tucson's most popular vacation spots for cycling, hiking, rock climbing, camping, birding, and wintertime snowboarding and skiing. Near the top of Mt. Lemmon is the town of Summerhaven. In Summerhaven, visitors will find log houses and cabins, a general store, and various shops, as well as numerous hiking trails. Near Summerhaven is the road to Ski Valley which hosts a ski lift, several runs, a giftshop, and nearby restaurant.

How many miles is Catalina Highway?

A:
25
