TOEFL Integrated Writing Task

Passage-1

In evolutionary biology, it is believed that many animal species engage in what is termed ‘warning calls.’ These are loud, distinct sounds made by a species member when a predator is near, alerting others to danger. This behavior is often seen as altruistic, as the individual making the call potentially increases its own risk of being noticed by the predator. This sacrificial behavior suggests that some animals prioritize the group’s safety over their own.

Transcript of the Lecture:

Professor: While warning calls are indeed widespread among animals, recent studies suggest they may not always be as altruistic as they seem. For instance, research on vervet monkeys indicates that the individual emitting the warning call increases its own survival chances. By alerting the predator to its awareness of the danger, it often causes the predator to abort the hunt, considering it compromised. Additionally, these calls can elevate the caller’s status within the group, leading to better mating opportunities and social standing. Thus, the motivation behind warning calls might be more about personal gain than previously thought.

Sample Answer:

The lecture provides new insights into the behavior of warning calls in animals, challenging the idea that these are purely altruistic acts as suggested in the reading passage. The professor points out that in species like vervet monkeys, the individual making the call actually benefits by potentially deterring the predator, as awareness of the danger can make the predator give up the hunt. This not only enhances the caller’s immediate survival prospects but also improves its social standing within the group, which can lead to superior mating opportunities. Therefore, the lecture suggests that the motivation behind warning calls may be driven more by self-interest than by the welfare of the group, casting doubt on the altruistic interpretation presented in the reading.

Passage-2

The concept of animals playing has long been interpreted as a way for young individuals to practice skills necessary for survival and hunting. This play, which includes mock fights and chase behaviors, is generally viewed as a crucial part of developmental growth, helping young animals enhance their physical abilities and social interactions in a relatively safe environment.

Transcript of the Lecture:

Professor: Recent research challenges the traditional view that animal play is purely for developing survival skills. Studies on juvenile wolves show that play also establishes and reinforces social hierarchies within packs. Young wolves that engage more frequently in play are often more successful in climbing the social ladder, leading to better access to resources and mating opportunities. Therefore, play may serve more complex social functions than merely skill development.

Sample Answer:

The lecture revises the traditional understanding of animal play, arguing against the reading passage’s claim that it solely aids in developing survival skills. According to the professor, play in species like juvenile wolves not only helps in skill enhancement but also plays a critical role in establishing social hierarchies. Frequent players tend to achieve higher social statuses, which grants them better access to resources and mates. This suggests that the purpose of play extends beyond physical and social skill development to include significant social stratification benefits, introducing a more strategic aspect to this behavior.

Passage-3

Birds are often observed participating in mutual grooming, a behavior thought to strengthen social bonds and promote group cohesion. This grooming, known as ‘preening,’ involves birds cleaning and arranging each other’s feathers, which is believed to enhance the health and welfare of the group by reducing parasites and stress levels.

Transcript of the Lecture:

Professor: While it’s true that mutual grooming in birds promotes health and social bonds, it also has a strategic component. Recent observations indicate that birds who engage more in grooming are more likely to receive support during conflicts or when food is scarce. Thus, grooming might also be a tactical investment in future assistance from other group members, rather than a purely selfless act.

Sample Answer:

The lecture introduces a strategic element to the behavior of mutual grooming in birds, which the reading passage describes as mainly for enhancing health and social cohesion. The professor explains that birds who participate more frequently in grooming activities are often better supported in times of need, such as during conflicts or food shortages. This suggests that mutual grooming is not solely about health or social bonds but also serves as a calculated investment in future reciprocal support, adding a layer of self-benefit to what might otherwise be seen as a communal activity.

Passage-4

Many marine animals are known to form large groups, or ‘schools,’ which are traditionally understood as a defense mechanism against predators. Schooling is believed to confuse predators and reduce the risk of individual attacks, suggesting a collective approach to survival where the safety of the group is prioritized over the individual.

Transcript of the Lecture:

Professor: The phenomenon of schooling among marine animals, while effective as a defense strategy, also serves individual interests. Research on schooling fish shows that individuals at the center of the school are less likely to be attacked than those on the outskirts. Therefore, fish compete for these safer central positions, indicating that the behavior may also be driven by individual survival instincts rather than solely by collective safety.

Sample Answer:

The lecture challenges the notion that schooling in marine animals is purely a collective defense mechanism, as stated in the reading passage. The professor highlights that while schooling does reduce the overall risk of predation, individuals within these groups are strategically competing for safer positions in the center, which are less susceptible to attacks. This competition suggests that schooling also reflects individual survival strategies, complicating the traditional view of this behavior as entirely group-oriented and altruistic.

Passage-5

In many species, migration is a behavior observed as a response to changing seasons, enabling animals to exploit different environments during specific periods for benefits such as breeding, feeding, or escaping harsh weather conditions. This seasonal movement is generally understood to optimize survival chances by allowing animals to take advantage of more favorable conditions and resources.

Transcript of the Lecture:

Professor: While migration certainly offers survival benefits as mentioned in the reading passage, recent studies have shown that this behavior also provides individual animals with competitive advantages. For instance, researchers studying caribou have observed that individuals who lead migrations often gain elevated social status and mating privileges within their groups. These leaders are usually the first to access new feeding grounds, enhancing their physical condition and reproductive success. Thus, migration can also serve as a platform for individual animals to improve their own social and reproductive standing, beyond the collective benefits of survival and resource optimization.

Sample Answer:

The lecture expands on the concept of migration discussed in the reading passage, introducing a component of individual benefit that contrasts with the traditional view of migration as a collective survival strategy. The professor explains that in species like caribou, the individuals who lead migrations do not only contribute to the group’s overall chances of finding better conditions but also enhance their own social and reproductive status. These leaders benefit from first access to resources in new environments, which boosts their physical health and increases their mating opportunities. This insight suggests that migration is not solely about communal advantages but also includes significant personal gains for certain individuals, challenging the purely altruistic perspective on this behavior.
