In the following passage, some of the words have been left out. Read the passage carefully and select the correct answer for the given blank out of the given alternative.
Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines. Petroleum is used to make gasoline, an important product in our everyday lives. Gasoline is also used in a spark-ignition engine. After ____(1)____ the fuel, you will see the production of a large amount of energy which happens when the ___(2)___ increases the temperature of the fuel. This temperature at which the fuel catches fire has a ___(3)_____value for every kind of fuel. Crude oil is usually black or dark brown, but can also be yellowish, reddish, tan, or even greenish. Colour variations indicate the distinct chemical compositions of different supplies of crude oil.
In order to ____(4)____ the smooth and uninterrupted flow of gasoline to the end-users, it is imperative for the field operators, pipeline engineers, and designers to be conscious of the corrosiveness of gasoline as the lines and their component fittings would ___(5)_____ material degradations due to corrosion.
The consequence of corrosion in the oil and gas industry cannot be ignored due to the damage caused to equipment and structures, and the huge cost of controlling it. Some case studies on the crude distillation overhead system, the economic cost of corrosion within the oil and gas industry, and the factors responsible for corrosion in crude distillation overhead system are discussed. Corrosion has been a major challenge in the oil and gas industry, ____(6)_____ in the crude distillation overhead system where the metallic structure used for construction and equipment are majorly affected by corrosion. However, to minimize corrosion costs in the oil and gas industry, the application of corrosion inhibitors and appropriate material selection is of utmost importance as stated in this report.
