According to paragraph 1, which of the following is true about petroleum formation?　A. Microscopic organisms that live in mud produce crude oil and natural gas.　B. Large amounts of oxygen are needed for petroleum formation to begin.　C. Petroleum is produced when organic material in sediments combines with decaying marine organisms.　D. Petroleum formation appears to begin in marine sediments where organic matter is present.　3.In paragraphs 1 and 2, the author’s primary purpose is to　A. describe how petroleum is formed　B. explain why petroleum formation is a slow process　C. provide evidence that a marine environment is necessary for petroleum formation　D. show that oil commonly occurs in association with gas　4. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.　A. Higher temperatures and pressures promote sedimentation, which is responsible for petroleum formation.　B. Deposits of sediments on top of organic matter increase the temperature of and pressure on the matter.　C. Increase pressure and heat from the weight of the sediment turn the organic remains into petroleum.　D. The remains of microscopic organisms transform into petroleum once they are buried under mud.　Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment. Microscopic organisms settle to the seafloor and accumulate in marine mud. The organic matter may partially decompose, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved.　Continued sedimentation—the process of deposits settling on the sea bottom—buries the organic matter and subjects it to hig
