Researchers at the University of Colombia have now demonstrated how smell may affect a person's emotional . Ninety-six couples were recruited for an experiment in the men were given shirts to wear for twenty-four hours. They had to avoid any products that could interfere with their own scent, such as tobacco, perfumes or spicy foods. The women were then given a shirt to sniff before taking in a stressful challenge. The research found that her levels of the stress hormone cortisol decreased if the shirt belonged to the woman's boyfriend or husband. These levels decreased even if the women were unaware whose shirt they were smelling, but they were lowest in women who recognized their partners' scents. Interestingly, women were chosen over men to be the ones who sniffed the clothing because they are known to have a sense of smell.

A.I. Explanation:

Correct answer: state
Explanation: The word 'state' fits grammatically as a noun that refers to a condition or situation, which aligns with the context of emotional impact. The phrase 'emotional state' is a common collocation, making it the most suitable choice.
Meaning: In this context, 'state' refers to a person's emotional condition or feelings at a given time.
Wrong options:
levels: The word 'levels' implies a measurement or quantity, which does not fit the context of describing emotions directly.
partners: The term 'partners' refers to individuals in a relationship, which is unrelated to the emotional condition being discussed.
women: The word 'women' does not relate to the emotional context and is irrelevant in this sentence.
Correct answer: which
Explanation: The word 'which' is a relative pronoun that introduces a non-defining clause, providing additional information about the experiment. It correctly connects the clause to the noun 'experiment' and maintains grammatical accuracy.
Meaning: 'Which' is used to specify or provide more information about something previously mentioned, in this case, the experiment.
Wrong options:
that: 'That' is a restrictive relative pronoun, which could fit but does not provide the same level of detail as 'which' in this context.
whose: 'Whose' indicates possession and does not grammatically fit with the structure of the sentence as it does not relate to the experiment directly.
where: 'Where' refers to a place, which does not apply to the context of describing the nature of the experiment.
Correct answer: part
Explanation: The word 'part' is a noun that fits grammatically and contextually, as it refers to participating in an activity. The phrase 'take part in' is a common idiomatic expression that indicates involvement in an event.
Meaning: 'Part' in this context means to participate or engage in an activity or challenge.
Wrong options:
turns: 'Turns' implies a change in direction or position, which does not fit the context of participating in a challenge.
apart: 'Apart' suggests separation, which is not relevant to the context of taking part in an activity.
away: 'Away' indicates distance or removal, which does not align with the idea of participating in a challenge.
Correct answer: of
Explanation: The preposition 'of' is used to indicate belonging or association, fitting grammatically and contextually with the phrase 'unaware of.' It correctly links the awareness to the shirt being smelled.
Meaning: 'Of' indicates a relationship or connection, in this case, the relationship between the women and the shirts they were smelling.
Wrong options:
which: 'Which' is a relative pronoun and does not fit as a preposition in this context.
in: 'In' suggests inclusion or location, which does not convey the intended meaning of awareness regarding the shirts.
at: 'At' indicates a specific location or time, which does not relate to the concept of awareness in this context.
Correct answer: better
Explanation: The word 'better' is a comparative adjective that fits grammatically and contextually, as it compares the sense of smell of women to that of men. It aligns with the structure of the sentence, indicating superiority.
Meaning: 'Better' means having a higher quality or greater ability, in this case, referring to women's superior sense of smell compared to men.
Wrong options:
larger: 'Larger' refers to size and does not apply to the context of sense or ability.
more: 'More' is a comparative adverb that requires a specific adjective to follow, making it grammatically incorrect here.
comparative: 'Comparative' is an adjective that describes a type of comparison but does not fit as a noun in this context.
