In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: Despite the need for strict deadlines, which sometimes excludes new scientific findings, what reveals a steady evolution of key findings?, Context: Since the IPCC does not carry out its own research, it operates on the basis of scientific papers and independently documented results from other scientific bodies, and its schedule for producing reports requires a deadline for submissions prior to the report's final release. In principle, this means that any significant new evidence or events that change our understanding of climate science between this deadline and publication of an IPCC report cannot be included. In an area of science where our scientific understanding is rapidly changing, this has been raised as a serious shortcoming in a body which is widely regarded as the ultimate authority on the science. However, there has generally been a steady evolution of key findings and levels of scientific confidence from one assessment report to the next.[citation needed]
[A]: assessment report

[Q]: Einstein created a way of thinking called a?, Context: It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.
[A]: theory

[Q]: Who owns the only railways in Israel?, Context: Israel has 18,096 kilometers (11,244 mi) of paved roads, and 2.4 million motor vehicles. The number of motor vehicles per 1,000 persons was 324, relatively low with respect to developed countries. Israel has 5,715 buses on scheduled routes, operated by several carriers, the largest of which is Egged, serving most of the country. Railways stretch across 949 kilometers (590 mi) and are operated solely by government-owned Israel Railways (All figures are for 2008). Following major investments beginning in the early to mid-1990s, the number of train passengers per year has grown from 2.5 million in 1990, to 35 million in 2008; railways are also used to transport 6.8 million tons of cargo, per year.
