Heat pumps are devices that use electricity to transfer heat from outside to inside a building, providing a clean and efficient way to heat homes. Heat pumps work by using a refrigerant, a material that changes state from liquid to gas and back , to absorb heat from the air, ground or water outside and transfer it to the water or air inside the building. This process can more energy than the electricity that is put into it, resulting in an energy efficiency of over 100%. They are considered a crucial technology for achieving the UK’s of reaching net zero emissions by 2040, as they can replace fossil fuel-based heating systems such as gas boilers. However, heat pumps are still uncommon in the UK, with only 1% of British homes having one installed, compared to 60% of Norwegian homes. The government aims to increase this number to 80% by 2048, and has recently a 50% increase in its boiler upgrade grants, which offer households up to £7,500 to switch to a heat pump.

Result:

A.I. Explanation:

Correct answer: again
Explanation: The word 'again' fits grammatically as it indicates the repetition of the process of changing state from liquid to gas and back, which is essential for the operation of heat pumps. It aligns contextually with the description of the refrigerant's cycle.
Meaning: 'Again' means 'once more' or 'another time,' indicating the cyclical nature of the refrigerant's state changes.
Wrong options:
yet: 'Yet' suggests something that has not happened up to this point, which does not fit the context of a repeated process.
aside: 'Aside' means 'to one side' or 'out of the way,' which does not relate to the process of changing states in this context.
around: 'Around' implies a circular movement or location, which does not accurately describe the process of changing states.
Correct answer: produce
Explanation: The verb 'produce' is appropriate here as it indicates the generation of energy, which is a key function of heat pumps. It fits grammatically and contextually, as the sentence discusses the energy output of the system.
Meaning: 'Produce' means 'to create or generate,' referring to the heat pump's ability to generate more energy than it consumes.
Wrong options:
imitate: 'Imitate' means to copy or mimic, which does not apply to the process of generating energy in this context.
deplete: 'Deplete' means to reduce or use up, which is the opposite of what heat pumps do in terms of energy generation.
conceal: 'Conceal' means to hide or keep something out of sight, which is irrelevant to the function of producing energy.
Correct answer: target
Explanation: The word 'target' is suitable as it refers to a specific goal or objective, which aligns with the context of the UK aiming for net zero emissions. It fits grammatically and contextually as a noun describing the goal.
Meaning: 'Target' means a goal or aim that one strives to achieve, in this case, the emissions goal set by the UK.
Wrong options:
term: 'Term' refers to a word or expression, which does not convey the idea of a goal in this context.
boundary: 'Boundary' implies a limit or edge, which does not fit the context of a goal or aim.
trend: 'Trend' refers to a general direction in which something is developing, which does not accurately describe a specific goal.
Correct answer: relatively
Explanation: The adverb 'relatively' is appropriate as it indicates a comparison, suggesting that heat pumps are uncommon compared to other heating systems. It fits grammatically and contextually within the sentence structure.
Meaning: 'Relatively' means 'in relation or comparison to something else,' indicating that heat pumps are uncommon when compared to other heating solutions.
Wrong options:
precisely: 'Precisely' means exactly or accurately, which does not convey the comparative nature needed in this context.
abruptly: 'Abruptly' means suddenly or unexpectedly, which does not fit the context of describing the commonality of heat pumps.
regularly: 'Regularly' means occurring at fixed intervals, which does not accurately describe the uncommon status of heat pumps.
Correct answer: announced
Explanation: The verb 'announced' is fitting as it indicates that the government has made a public declaration regarding the increase in grants. It fits grammatically and contextually as it describes an action taken by the government.
Meaning: 'Announced' means to make a public statement about something, in this case, the increase in boiler upgrade grants.
Wrong options:
underestimated: 'Underestimated' means to assess something as less than its actual value, which does not fit the context of making a declaration.
diverted: 'Diverted' means to change the direction of something, which does not apply to the context of announcing a grant increase.
told: 'Told' is a more informal way of saying to inform someone, but it lacks the formal context needed for a government announcement.
