Meaning: 'Plastic' refers to synthetic materials that are widely used but often contribute to pollution and environmental harm when not disposed of properly.

Wrong options:

• digital: 'Digital' relates to electronic data and does not pertain to physical waste, making it irrelevant in this context.
• emotional: 'Emotional' pertains to feelings and does not relate to waste, thus it does not fit the context of reducing physical waste.
• auditory: 'Auditory' relates to sound and is not applicable to the concept of waste, making it an incorrect choice.

Correct answer: minimise

Explanation: The word 'minimise' is appropriate as it directly relates to reducing energy consumption, aligning with the context of lowering one's carbon footprint. It fits grammatically as a verb that complements the action of consumption.

Meaning: 'Minimise' means to make something as small as possible, particularly in terms of quantity or impact, which is relevant to energy use.

Wrong options:

• maximise: 'Maximise' means to increase to the greatest possible amount, which contradicts the goal of reducing energy consumption.
• stabilise: 'Stabilise' implies making something steady or unchanging, which does not convey the action of reducing consumption.
• publicise: 'Publicise' means to make something known to the public, which is unrelated to the context of energy consumption.

Correct answer: local

Explanation: The word 'local' fits well as it emphasizes supporting nearby businesses, which is a key aspect of sustainable living. It aligns grammatically and contextually with the idea of promoting a greener economy.

Meaning: 'Local' refers to businesses or products that are situated nearby, often supporting the community and reducing transportation emissions.

Wrong options:

• distant: 'Distant' implies far away, which contradicts the idea of supporting nearby businesses.
• online: 'Online' refers to businesses that operate on the internet, which does not necessarily support local economies.
• multinational: 'Multinational' refers to companies operating in multiple countries, which may not contribute to local economies and sustainability.

Correct answer: reduce

Explanation: The word 'reduce' is the most fitting choice as it directly correlates with the goal of lowering emissions through alternative transportation methods. It fits grammatically as a verb that complements the subject of the sentence.

Meaning: 'Reduce' means to make something smaller or less in amount, which is relevant to the context of emissions from transportation.

Wrong options:

• increase: 'Increase' means to make larger or greater, which is the opposite of the intended action of lowering emissions.
• maintain: 'Maintain' implies keeping the same level, which does not align with the goal of reducing emissions.
• ignore: 'Ignore' means to pay no attention to, which is not relevant to the context of actively reducing emissions.
