Meaning: 'Non-recyclable' refers to materials that cannot be recycled and must be disposed of in landfills.

Wrong options:

• refuse: 'Refuse' refers to waste or garbage in general but does not specifically indicate what type of waste is being reduced, making it less precise in this context.
• attitudes: 'Attitudes' refers to people's feelings or opinions, which does not fit as it does not describe a type of waste.
• biodegradable: 'Biodegradable' refers to materials that can decompose naturally, which is the opposite of what is being discussed here, as it implies these materials can be processed rather than sent to landfills.
• compost: 'Compost' is a product of decomposed organic matter, which does not fit as it is not a type of waste but rather a beneficial end product of waste management.
• renewable resources: 'Renewable resources' refers to materials that can be replenished naturally, which does not fit the context of waste being sent to landfills.
• glass: 'Glass' is a specific type of material that can be recycled, but it does not encompass the broader category of waste being referred to.

Correct answer: renewable resources

Explanation: The phrase 'renewable resources' fits grammatically as it serves as the object of the verb 'turn.' Contextually, it refers to materials that can be replenished and are suitable for recycling, which aligns with the purpose of recycling programs.

Meaning: 'Renewable resources' are materials that can be naturally replenished, such as certain types of paper, wood, and some plastics.

Wrong options:

• refuse: 'Refuse' refers to waste or garbage in general, which does not fit as it does not indicate materials that can be recycled into useful products.
• attitudes: 'Attitudes' refers to people's feelings or opinions, which is irrelevant in the context of recycling materials.
• biodegradable: 'Biodegradable' refers to materials that can decompose naturally, which does not fit as it does not imply they are being turned into products through recycling.
• compost: 'Compost' is a product of decomposed organic matter, not a resource that can be turned into products through recycling.
• non-recyclable: 'Non-recyclable' refers to materials that cannot be recycled, which contradicts the purpose of recycling programs.
• glass: 'Glass' is a specific recyclable material, but it does not encompass the broader category of renewable resources.

Correct answer: compost

Explanation: The word 'compost' fits grammatically as it serves as the object of the verb 'creating.' Contextually, it refers to the beneficial product derived from organic waste, which is relevant to urban gardening projects.

Meaning: 'Compost' is a mixture of organic matter, such as food scraps and yard waste, that has decomposed and is used as a fertilizer.

• attitudes: 'Attitudes' refers to people's feelings or opinions, which is irrelevant in the context of creating a product from waste.
• biodegradable: 'Biodegradable' refers to materials that can decompose naturally, which does not fit as it does not describe a product created from organic waste.
• non-recyclable: 'Non-recyclable' refers to materials that cannot be recycled, which does not fit as it is not a product of composting.
• renewable resources: 'Renewable resources' refers to materials that can be replenished, which does not fit as it does not describe the end product of composting.
• glass: 'Glass' is a specific recyclable material, not a product of composting.

Correct answer: attitudes

Explanation: The term 'attitudes' fits grammatically as it serves as the object of the verb 'changing.' Contextually, it refers to the mindset of the public regarding waste disposal and recycling, which is crucial for effective waste management.

Meaning: 'Attitudes' refers to people's feelings or opinions about a particular subject, in this case, waste disposal and recycling.

Wrong options:

• refuse: 'Refuse' refers to waste or garbage in general, which does not fit as it does not describe a mindset or opinion.

• compost: 'Compost' is a product of decomposed organic matter, which does not fit as it is not related to public opinion.
• non-recyclable: 'Non-recyclable' refers to materials that cannot be recycled, which does not fit as it does not describe a mindset.
• renewable resources: 'Renewable resources' refers to materials that can be replenished, which does not fit as it does not describe attitudes or opinions.
• glass: 'Glass' is a specific recyclable material, which does not fit as it does not relate to public attitudes.
