Article: There is an environmental program, called Hoy No Circula ("Today Does Not Run", or "One Day without a Car"), whereby vehicles that have not passed emissions testing are restricted from circulating on certain days according to the ending digit of their license plates; this in an attempt to cut down on pollution and traffic congestion. While in 2003, the program still restricted 40% of vehicles in the metropolitan area, with the adoption of stricter emissions standards in 2001 and 2006, in practice, these days most vehicles are exempt from the circulation restrictions as long as they pass regular emissions tests.

Question: How do people know which days to not drive their car?
Ans: ending digit of their license plates


Article: While Old Czech had a basic alphabet from which a general set of orthographical correspondences was drawn, it did not have a standard orthography. It also contained a number of sound clusters which no longer exist; allowing ě (/jɛ/) after soft consonants, which has since shifted to e (/ɛ/), and allowing complex consonant clusters to be pronounced all at once rather than syllabically. A phonological phenomenon, Havlik's law (which began in Proto-Slavic and took various forms in other Slavic languages), appeared in Old Czech; counting backwards from the end of a clause, every odd-numbered yer was vocalized as a vowel, while the other yers disappeared.

Question: What type of orthography did Old Czech lack?
Ans: standard


Article: One important aspect of the rule-of-law initiatives is the study and analysis of the rule of law’s impact on economic development. The rule-of-law movement cannot be fully successful in transitional and developing countries without an answer to the question: does the rule of law matter for economic development or not? Constitutional economics is the study of the compatibility of economic and financial decisions within existing constitutional law frameworks, and such a framework includes government spending on the judiciary, which, in many transitional and developing countries, is completely controlled by the executive. It is useful to distinguish between the two methods of corruption of the judiciary: corruption by the executive branch, in contrast to corruption by private actors.

Question: In developing countries, who makes most of the spending decisions?
Ans: the executive


Article: In March 2013, the Blackstone Group and Carl Icahn expressed interest in purchasing Dell. In April 2013, Blackstone withdrew their offer, citing deteriorating business. Other private equity firms such as KKR & Co. and TPG Capital declined to submit alternative bids for Dell, citing the uncertain market for personal computers and competitive pressures, so the "wide-open bidding war" never materialized. Analysts said that the biggest challenge facing Silver Lake would be to find an “exit strategy” to profit from its investment, which would be when the company would hold an IPO to go public again, and one warned “But even if you can get a $25bn enterprise value for Dell, it will take years to get out.”

Question: What company did analysts feel would need to find an exit strategy to profit from acquiring Dell?
Ans:
Silver Lake
