[Q]: Passage: Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb-rows than modern forms, have been found in lagerstätten as far back as the early Cambrian, about 515 million years ago. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. A recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid-like, and that all the modern groups appeared relatively recently, probably after the Cretaceous–Paleogene extinction event 66 million years ago. Evidence accumulating since the 1980s indicates that the 'cydippids' are not monophyletic, in other words do not include all and only the descendants of a single common ancestor, because all the other traditional ctenophore groups are descendants of various cydippids. Question: What were the fossils that were found to represent ctenphores missing that current ctenphora have?
[A]: tentacles


[Q]: Passage: On October 6, 1973, Syria and Egypt, with support from other Arab nations, launched a surprise attack on Israel, on Yom Kippur. This renewal of hostilities in the Arab–Israeli conflict released the underlying economic pressure on oil prices. At the time, Iran was the world's second-largest oil exporter and a close US ally. Weeks later, the Shah of Iran said in an interview: 'Of course [the price of oil] is going to rise... Certainly! And how!... You've [Western nations] increased the price of the wheat you sell us by 300 percent, and the same for sugar and cement... You buy our crude oil and sell it back to us, refined as petrochemicals, at a hundred times the price you've paid us... It's only fair that, from now on, you should pay more for oil. Let's say ten times more.' Question: Who was the world's second largest oil producer?
[A]: Iran


[Q]: Passage: In India, private schools are called independent schools, but since some private schools receive financial aid from the government, it can be an aided or an unaided school. So, in a strict sense, a private school is an unaided independent school. For the purpose of this definition, only receipt of financial aid is considered, not land purchased from the government at a subsidized rate. It is within the power of both the union government and the state governments to govern schools since Education appears in the Concurrent list of legislative subjects in the constitution. The practice has been for the union government to provide the broad policy directions while the states create their own rules and regulations for the administration of the sector. Among other things, this has also resulted in 30 different Examination Boards or academic authorities that conduct examinations for school leaving certificates. Prominent Examination Boards that are present in multiple states are the CBSE and the CISCE, NENBSE Question: How many Examination Boards exist in India?
[A]:
30
