Practice Reading: Multiple Choice, Single Answer ID: #36169 Hexafluoride
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Emissions of sulphur hexafluoride, the strongest greenhouse gas in the Earth’s atmosphere, have increased dramatically in the past few years. This colourless greenhouse gas has multiple uses, including acting as an insulator in electrical installations. Aside from being an insulator in circuit breakers and switches, sulphur hexafluoride is utilised to inhibit fires. However, when installed, it does result in some emissions into the atmosphere. Renewable energy installations require more circuit breakers and switches in their electricity grids due to having more wind turbines and solar panels. Therefore, as renewable energy production expands, there is likely to be an associated rise in sulphur hexafluoride emissions.

Option 2: "Producing more renewable energy may lead to more sulphur hexafluoride emissions."

Explanation: This option accurately reflects the main point of the text. The author discusses how the expansion of renewable energy production, which requires more circuit breakers and switches, is likely to result in increased emissions of sulphur hexafluoride. This is supported by the text's statement about the correlation between renewable energy installations and sulphur hexafluoride emissions.

Option 1: "Sulphur hexafluoride has a wide variety of uses in renewable energy production."

Explanation: While the text mentions that sulphur hexafluoride has multiple uses, it does not specifically state that these uses are primarily in renewable energy production. The focus of the text is on the emissions associated with increased renewable energy installations, not on the variety of uses of sulphur hexafluoride.

Option 3: "It is becoming increasingly difficult and complicated to generate renewable energy."

Explanation: This option introduces a new idea that is not present in the text. The text does not discuss the difficulty or complexity of generating renewable energy; instead, it focuses on the emissions related to the increased use of sulphur hexafluoride due to renewable energy installations.

Option 4: "Green energy demands ultimately result in emissions of various greenhouse gases."

Explanation: While this option touches on the theme of emissions, it is too broad and does not specifically address the main point of the text regarding sulphur hexafluoride. The text specifically highlights the relationship between renewable energy production and sulphur hexafluoride emissions, rather than a general statement about various greenhouse gases.
