Problem: Please answer a question about the following article about Compact disc:
Replicated CDs are mass-produced initially using a hydraulic press. Small granules of heated raw polycarbonate plastic are fed into the press. A screw forces the liquefied plastic into the mold cavity. The mold closes with a metal stamper in contact with the disc surface. The plastic is allowed to cool and harden. Once opened, the disc substrate is removed from the mold by a robotic arm, and a 15 mm diameter center hole (called a stacking ring) is created. The time it takes to "stamp" one CD is usually two to three seconds.
What type of material is used to make CDs?
A: raw polycarbonate plastic
Problem: Please answer a question about the following article about Karl Popper:
Popper coined the term "critical rationalism" to describe his philosophy. Concerning the method of science, the term indicates his rejection of classical empiricism, and the classical observationalist-inductivist account of science that had grown out of it. Popper argued strongly against the latter, holding that scientific theories are abstract in nature, and can be tested only indirectly, by reference to their implications. He also held that scientific theory, and human knowledge generally, is irreducibly conjectural or hypothetical, and is generated by the creative imagination to solve problems that have arisen in specific historico-cultural settings.
What was Popper's position on classical empiricism?
A: rejection
Problem: Please answer a question about the following article about Premier League:
The years following 2009 marked a shift in the structure of the "Big Four" with Tottenham Hotspur and Manchester City both breaking into the top four. In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005. Criticism of the gap between an elite group of "super clubs" and the majority of the Premier League has continued, nevertheless, due to their increasing ability to spend more than the other Premier League clubs. Manchester City won the title in the 201112 season, becoming the first club outside the "Big Four" to win since 199495. That season also saw two of the Big Four (Chelsea and Liverpool) finish outside the top four places for the first time since 199495.
Which team finished fourth in the 2009-10 season?
A: In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005
Problem: Please answer a question about the following article about Flowering plant:
In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
What results from the development of xylem on the inside and phloem on the outside?
A:
increase in thickness
