Problem: Please answer a question about the following article about Samoa:
In the period before German colonisation, Samoa produced mostly copra. German merchants and settlers were active in introducing large scale plantation operations and developing new industries, notably cocoa bean and rubber, relying on imported labourers from China and Melanesia. When the value of natural rubber fell drastically, about the end of the Great War (World War I), the New Zealand government encouraged the production of bananas, for which there is a large market in New Zealand.[citation needed]
What product significantly dropped in price at the end of World War I?
A: natural rubber
Problem: Please answer a question about the following article about Group (mathematics):
Lie groups are of fundamental importance in modern physics: Noether's theorem links continuous symmetries to conserved quantities. Rotation, as well as translations in space and time are basic symmetries of the laws of mechanics. They can, for instance, be used to construct simple modelsimposing, say, axial symmetry on a situation will typically lead to significant simplification in the equations one needs to solve to provide a physical description.v["] Another example are the Lorentz transformations, which relate measurements of time and velocity of two observers in motion relative to each other. They can be deduced in a purely group-theoretical way, by expressing the transformations as a rotational symmetry of Minkowski space. The latter servesin the absence of significant gravitationas a model of space time in special relativity. The full symmetry group of Minkowski space, i.e. including translations, is known as the Poincare group. By the above, it plays a pivotal role in special relativity and, by implication, for quantum field theories. Symmetries that vary with location are central to the modern description of physical interactions with the help of gauge theory.
What describe the complete symmetry group of Minkowski space including translations?
A: Poincare group
Problem: Please answer a question about the following article about Sexual orientation:
In the United States, non-Caucasian LGBT individuals may find themselves in a double minority, where they are neither fully accepted or understood by mainly Caucasian LGBT communities, nor are they accepted by their own ethnic group. Many people experience racism in the dominant LGBT community where racial stereotypes merge with gender stereotypes, such that Asian-American LGBTs are viewed as more passive and feminine, while African-American LGBTs are viewed as more masculine and aggressive. There are a number of culturally specific support networks for LGBT individuals active in the United States. For example, "O-Moi" for Vietnamese American queer females.
What is an example of a stereotype found in this double minority?
A: Asian-American LGBTs are viewed as more passive and feminine
Problem: Please answer a question about the following article about Compact disc:
The CD was planned to be the successor of the gramophone record for playing music, rather than primarily as a data storage medium. From its origins as a musical format, CDs have grown to encompass other applications. In 1983, following the CD's introduction, Immink and Braat presented the first experiments with erasable compact discs during the 73rd AES Convention. In June 1985, the computer-readable CD-ROM (read-only memory) and, in 1990, CD-Recordable were introduced, also developed by both Sony and Philips. Recordable CDs were a new alternative to tape for recording music and copying music albums without defects introduced in compression used in other digital recording methods. Other newer video formats such as DVD and Blu-ray use the same physical geometry as CD, and most DVD and Blu-ray players are backward compatible with audio CD.
What year was the 73rd AES Convention?
A:
1983
