Tips: Use the stated detail rather than guessing speaker order or an unstated commitment.

Why the other options are wrong:

• From an article in the newspaper.: The article was in the recommended journal, not a newspaper.
• During a lecture on coffee.: A lecture is not identified as the information source.
• From one of his friends.: Bob reports reading the article himself; a friend is not the source.

Correct Answer: Three.

Why this is correct: The conversation names three bean types: Robusta, Arabica and Librica.

Tips: Use the stated detail rather than guessing speaker order or an unstated commitment.

Why the other options are wrong:

• One.: Robusta is not the only type; Arabica and Librica are also named.
• Two.: The initial two types are followed by a third, Librica.
• Five.: Only Robusta, Arabica and Librica are named, not five types.

Correct Answer: Each producing zone has a peculiar flavour of coffee.

Why this is correct: The conversation explicitly mentions country-based flavour variation; the other statements are unsupported or contradicted.

Tips: Use the stated detail rather than guessing speaker order or an unstated commitment.

Why the other options are wrong:

• Bob and Teresa were doing a project on coffee.: No coffee project is mentioned.
• Their professor had written an article on coffee in a journal.: Professor Smith recommended the journal; the conversation does not say he wrote the article.
• Generally, the coffee producers have large land holdings.: The article describes most growers as farmers with four or five hectares, contradicting large holdings.

Correct Answer: In blended coffees.

Why this is correct: The conversation introduces Robusta, then Arabica, then one more type named Librica. The next description says that third type is used in blended coffees.

Tips: Choose the statement supported by the conversation.

Why the other options are wrong:

• In instant coffee.: Instant coffee is associated with Robusta, the first type, rather than the third type.
• As espresso.: Espresso is not identified as a use of the third type.
• Only at higher temperatures.: The conversation gives growing altitudes, not a claim that the third type is used only at higher temperatures.

Correct Answer: It is cultivated in higher regions.

Why this is correct: Arabica is explicitly said to be grown higher up, between 600 and 2000 metres. The stem limits the statement to Arabica rather than all coffee.

Tips: Choose the statement supported by the conversation.

Why the other options are wrong:

• It is grown in any land form.: The source gives a bounded altitude range for Arabica, not unrestricted land forms.
• It has higher yield if grown once a year.: The conversation makes no claim about greater yield from growing Arabica once a year.
• It is planted only in hot zones.: Only hot zones is not stated; the source describes altitude rather than an exclusive climate zone.
