Practice Reading: Multiple Choice, Single Answer ID: #5576 Energy 2
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Huge reserves of energy have been found in rocks far below the surface of the ground in Britain. It is estimated that the north and southwest regions could hold enough energy in the form of heat to provide power for millions of homes. In fact, up to a fifth of Britain's energy could be provided by this geothermal source. Extracting the heat and converting it into electricity is difficult and expensive. Thousands of bore holes would be needed; but once they were in place, the heat would keep regenerating indefinitely.

Option 3: "to highlight the potential benefits of geothermal power for Britain"

Explanation: This option is correct as the text discusses the significant energy reserves in Britain and suggests that geothermal power could provide energy for millions of homes. The main purpose is to highlight these potential benefits, making this option the best fit.

Option 1: "to show how common the use of geothermal power is in Britain"

Explanation: This option is incorrect because the text does not discuss the prevalence or commonality of geothermal power usage in Britain. Instead, it focuses on the potential energy reserves and their benefits, rather than how widely geothermal power is currently used.

Option 2: "to describe the problems related to using geothermal power in Britain"

Explanation: While the text mentions that extracting heat is difficult and expensive, it does not primarily focus on the problems. Instead, it emphasizes the potential energy reserves and benefits, making this option too narrow and not aligned with the main purpose.

Option 4: "to give a detailed description of how geothermal energy is produced in Britain"

Explanation: This option is incorrect because the text does not provide a detailed description of the production process of geothermal energy. It only mentions the extraction and conversion challenges briefly, without going into specifics about how geothermal energy is produced.
