Correct answer: have been known
Explanation: The phrase 'have been known' is in the present perfect passive form, indicating that the lyrebirds have a long-standing reputation for their ability to mimic sounds. This fits grammatically as it suggests an ongoing state that began in the past and continues to the present, aligning with the context of their mimicking abilities.
Meaning: 'Have been known' means that it is widely recognized or acknowledged that lyrebirds can replicate various sounds.
Wrong options:
- are being known: This option is incorrect because 'are being known' suggests a current process of becoming known, which does not fit the established reputation of lyrebirds.
- are knowing: This option is incorrect as 'are knowing' is not a standard usage in English; it implies an active process of knowing, which does not apply here.
- know: This option is incorrect because 'know' is a simple present tense that does not convey the ongoing recognition of their mimicking abilities.
Correct answer: mates
Explanation: The word 'mates' is the most appropriate term in this context, referring to potential partners in a biological sense. It fits grammatically and contextually, as it aligns with the idea of reproduction and attraction in the animal kingdom.
Meaning: 'Mates' refers to partners in a reproductive context, particularly in the animal world, indicating those with whom the male lyrebird seeks to pair.
Wrong options:
- companions: This option is incorrect because 'companions' implies friendship rather than a reproductive relationship, which is not the focus here.
- spouses: This option is incorrect as 'spouses' suggests a formalized relationship, which is not typically used in the context of animal mating behavior.
- pairs: This option is incorrect because 'pairs' is a general term that does not specifically denote potential reproductive partners.
Correct answer: take part
Explanation: The phrase 'take part' is an idiomatic expression meaning to participate in an activity. It fits grammatically and contextually, as it indicates that female lyrebirds do not engage in the act of mimicking sounds.
Meaning: 'Take part' means to participate or be involved in something, indicating that female lyrebirds do not engage in the mimicking process.
Wrong options:
- put forward: This option is incorrect because 'put forward' means to propose or suggest something, which does not relate to participation in mimicking.
- take place: This option is incorrect as 'take place' refers to an event occurring, not to participation in an activity.
- work out: This option is incorrect because 'work out' implies solving a problem or exercising, which does not fit the context of mimicking sounds.
Correct answer: still
Explanation: The word 'still' indicates that the action continues to occur despite the passage of time, fitting grammatically and contextually as it emphasizes the ongoing ability of lyrebirds to recreate sounds that are no longer in use.
Meaning: 'Still' means 'up to now' or 'continuing to happen,' highlighting that these lyrebirds continue to mimic sounds that have not been used for years.
Wrong options:
- indeed: This option is incorrect because 'indeed' is an affirmation and does not convey the sense of continuity required in this context.
- just: This option is incorrect as 'just' implies a recent action or a limitation in time, which does not fit the ongoing nature of the lyrebirds' abilities.
- yet: This option is incorrect because 'yet' suggests something that has not happened up to this point, which contradicts the idea of ongoing mimicry.
