Problem: Portugal:

The country bounced between socialism and adherence to the neoliberal model. Land reform and nationalizations were enforced; the Portuguese Constitution (approved in 1976) was rewritten in order to accommodate socialist and communist principles. Until the constitutional revisions of 1982 and 1989, the constitution was a highly charged ideological document with numerous references to socialism, the rights of workers, and the desirability of a socialist economy. Portugal's economic situation after its transition to democracy, obliged the government to pursue International Monetary Fund (IMF)-monitored stabilization programs in 197778 and 198385.

For what reasons were the Portuguese Constitution rewritten?
---
A: to accommodate socialist and communist principles

Problem: Buddhism:

Mahayana schools recognize all or part of the Mahayana Sutras. Some of these sutras became for Mahayanists a manifestation of the Buddha himself, and faith in and veneration of those texts are stated in some sutras (e.g. the Lotus Sutra and the Mahaparinirvana Sutra) to lay the foundations for the later attainment of Buddhahood itself.

Mahayana schools recognize all or part of what?
---
A: Mahayana Sutras

Problem: Sichuan:

Due to great differences in terrain, the climate of the province is highly variable. In general it has strong monsoonal influences, with rainfall heavily concentrated in the summer. Under the Koppen climate classification, the Sichuan Basin (including Chengdu) in the eastern half of the province experiences a humid subtropical climate (Koppen Cwa or Cfa), with long, hot, humid summers and short, mild to cool, dry and cloudy winters. Consequently, it has China's lowest sunshine totals. The western region has mountainous areas producing a cooler but sunnier climate. Having cool to very cold winters and mild summers, temperatures generally decrease with greater elevation. However, due to high altitude and its inland location, many areas such as Garze County and Zoige County in Sichuan exhibit a subarctic climate (Koppen Dwc)- featuring extremely cold winters down to -30 C and even cold summer nights. The region is geologically active with landslides and earthquakes. Average elevation ranges from 2,000 to 3,500 meters; average temperatures range from 0 to 15 C. The southern part of the province, including Panzhihua and Xichang, has a sunny climate with short, very mild winters and very warm to hot summers.

What climate classification does the Sichuan Basin hold?
---
A: humid subtropical climate

Problem: Incandescent light bulb:

Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament. Incandescent light bulbs usually contain a stem or glass mount anchored to the bulb's base that allows the electrical contacts to run through the envelope without air or gas leaks. Small wires embedded in the stem in turn support the filament and its lead wires.

What allows air or gas leaks in the bulb's base?
---
A:
unanswerable
