A.I. Explanation:

Correct answer: trend

Explanation: The word 'trend' fits grammatically as a noun that describes a general direction in which something is developing or changing. In this context, it refers to the rising preference for sustainable products among consumers, particularly millennials. The sentence structure supports this noun, as it follows 'this' which indicates a specific subject being discussed.

Meaning: 'Trend' means a general tendency or direction in which something is developing or changing, in this case, the increasing preference for sustainable products.

Wrong options:

• duty: The word 'duty' refers to a moral or legal obligation, which does not fit the context of consumer preferences and trends.
• balance: 'Balance' implies an equal distribution or stability, which does not accurately describe the rising preference for sustainable products.
• context: 'Context' refers to the circumstances surrounding an event or situation, which does not align with the idea of a growing consumer preference.

Correct answer: take

Explanation: The verb 'take' is correctly used here to indicate that brands are expected to assume or accept social responsibility. It fits grammatically as it follows the structure 'take social responsibility seriously,' which is a common collocation in English.

Meaning: 'Take' in this context means to assume or accept something, indicating that brands should actively engage in social responsibility.

Wrong options:

• get: 'Get' implies receiving or obtaining, which does not convey the active engagement required in the context of social responsibility.
• raise: 'Raise' typically means to lift or elevate, which does not fit the context of assuming responsibility.
• make: 'Make' suggests creating or causing something, which does not accurately convey the idea of accepting or taking on social responsibility.

Correct answer: from

Wrong options:

• into: 'Into' suggests movement toward the inside of something, which does not fit the context of distinguishing between two types of companies.
• for: 'For' indicates purpose or benefit, which does not convey the idea of separation or distinction required in this context.
• away: 'Away' implies distance or removal, which does not accurately describe the relationship between ethical brands and fast fashion companies.

Correct answer: significant

Meaning: 'Significant' means important or noteworthy, indicating that the change in market dynamics towards ethical products is substantial.

Wrong options:

• respective: 'Respective' refers to something relating to each of two or more things, which does not fit the context of describing the importance of a change.
