Meaning: 'Range' refers to a variety or selection of different things, in this case, human characteristics that vary among individuals and groups.

Wrong options:

• hoard: Hoard implies accumulation or storage, which does not fit the context of discussing diversity as it suggests possession rather than variety.
• set: Set refers to a collection of items but lacks the nuance of variety that 'range' conveys, making it less suitable in this context.
• sense: Sense refers to perception or understanding, which does not relate to the concept of diversity as a variety of characteristics.

Correct answer: which

Explanation: The word 'which' is the correct relative pronoun that introduces the clause describing the demographic and psychographic factors. It connects the factors to the previous noun phrase, maintaining grammatical coherence.

Meaning: 'Which' is used to introduce a clause that provides additional information about the factors being discussed, specifically identifying them as traditionally used by marketers.

Wrong options:

• them: 'Them' is an object pronoun and does not function correctly as a relative pronoun to introduce the clause, making it grammatically incorrect here.
• who: 'Who' is a subject pronoun typically used for people, but in this context, 'which' is more appropriate as it refers to the factors, not individuals.
• whom: 'Whom' is an object pronoun and is not suitable here as it does not correctly introduce the clause related to the factors.

Correct answer: traits

Explanation: The word 'traits' fits grammatically as it refers to characteristics or qualities, which aligns perfectly with the context of demographic factors describing the 'who'.

Meaning: 'Traits' refers to distinguishing characteristics or qualities of individuals, such as age, education, and gender, which are relevant in demographic analysis.

Wrong options:

• baits: 'Baits' refers to something used to attract or entice, which is unrelated to the context of demographic characteristics.
• straits: 'Straits' refers to narrow passages or difficult situations, which does not apply to the context of describing human characteristics.
• gaits: 'Gaits' refers to the manner of walking, which is not relevant to the discussion of demographic factors.

Correct answer: reflect

Explanation: The word 'reflect' is appropriate as it indicates that psychographic factors show or demonstrate our behavior and beliefs, fitting grammatically and contextually within the sentence.

Meaning: 'Reflect' means to show or express something, in this case, how our beliefs and values are represented in our behavior.

Wrong options:

• project: 'Project' implies to present or display outwardly, which does not accurately convey the idea of internal beliefs being shown through behavior.
• reject: 'Reject' means to refuse or dismiss, which is contrary to the intended meaning of showing or demonstrating behavior and beliefs.
• deject: 'Deject' means to make someone feel sad or depressed, which does not fit the context of discussing how factors relate to behavior.

Correct answer: discrimination

Explanation: The word 'discrimination' fits grammatically and contextually as it refers to unfair treatment based on differences, which is the focus of the sentence regarding legal protections.

Meaning: 'Discrimination' refers to the unjust or prejudicial treatment of different categories of people, which is relevant in the context of diversity and legal protections.

Wrong options:

• confrontation: 'Confrontation' refers to a hostile or argumentative meeting, which does not relate to the context of legal protections against unfair treatment.
• degradation: 'Degradation' implies a decline in quality or respect, which does not specifically address the legal aspect of unfair treatment based on diversity.
• contamination: 'Contamination' refers to the act of making something impure or unsuitable, which is unrelated to the context of discrimination in diversity.
