Meaning: 'Without' means 'in the absence of' or 'not having,' indicating that cannabis compounds can be produced in labs without needing the actual plant.

Wrong options:

• regarding: 'Regarding' suggests a topic of discussion but does not fit grammatically as it does not indicate absence or condition in this context.
• due to: 'Due to' implies a cause-and-effect relationship, which does not align with the intended meaning of producing compounds without the plant.
• although: 'Although' introduces a contrast, which is not appropriate here as the sentence does not present a conflicting idea.

Correct answer: purposes

Explanation: The word 'purposes' fits grammatically and contextually as it refers to the intended uses of cannabinoids, aligning with the plural form needed in this context.

Meaning: 'Purposes' means 'the reasons for which something is done or created,' indicating the various uses of cannabinoids in medical and recreational contexts.

Wrong options:

• angles: 'Angles' refers to perspectives or approaches, which does not fit the context of intended uses for cannabinoids.
• sequences: 'Sequences' implies an order or arrangement, which is irrelevant to the context of uses for cannabinoids.
• phases: 'Phases' suggests stages in a process, which does not accurately represent the intended meaning of uses in this context.

Correct answer: overlooked

Explanation: The word 'overlooked' appropriately describes the environmental impact as something that is often ignored or not given due attention, fitting grammatically and contextually within the sentence.

Meaning: 'Overlooked' means 'not noticed or considered,' indicating that the environmental impact of cannabis production is frequently neglected.

Wrong options:

• tailored: 'Tailored' suggests something that is customized or adjusted, which does not fit the context of environmental impact being ignored.
• contained: 'Contained' implies something is held within limits, which does not convey the idea of neglecting the environmental impact.

Correct answer: emissions

Explanation: The word 'emissions' fits grammatically and contextually as it refers to the release of greenhouse gases, which is a direct consequence of cannabis production, aligning with the plural form needed here.

Meaning: 'Emissions' refers to the act of releasing substances, particularly gases, into the atmosphere, indicating the environmental consequences of cannabis cultivation.

Wrong options:

• conditions: 'Conditions' refers to the state of something, which does not fit the context of gases being released.
• resources: 'Resources' implies materials or assets, which does not accurately describe the byproducts of cannabis production.
• customs: 'Customs' refers to traditional practices or duties, which is unrelated to the environmental impact of cannabis cultivation.
