Task Overview

Reading Passage

Swarm Intelligence Some insect species live in large groups, or “swarms.” Such swarms typically include several thousand individual insects. Living in swarms allows these insects to accomplish complex tasks together through complex behaviors. The behavior of the insects as a group demonstrates greater level of complexity than the behavior of individual group members. This complex group behavior is called swarm intelligence. With swarm intelligence, each insect performs a simple instinctual behavior that is repeated by other individual that results in a complex behavior. Insect swarms are able to accomplish tasks that individual insects would not be able to achieve.

Delivery The speaker's delivery is generally clear and fluid, but there are some occasional pauses that could be improved. To enhance the delivery, the speaker should practice speaking more consistently and work on reducing unnecessary pauses. Additionally, focusing on accurate pronunciation will help eliminate any spelling errors that may have resulted from mispronunciations.
Topic Development The speaker did an excellent job in developing the topic by providing a coherent and well-organized response. The example of ants forming a bridge to overcome obstacles clearly illustrates the concept of swarm intelligence. The speaker effectively connected ideas and provided sufficient support for their explanation. To further improve, the speaker could consider adding more examples or elaborating on the significance of swarm intelligence in other contexts.

5. Language Use

Original Answer: Swarm intelligence refers to insects that live in large groups and each individual insect is assigned with simple instinctive actions that ultimately the group completes a complex task where one single insect would not be able to achieve. Swarm intelligence involves insects living in large groups, with each individual insect performing simple instinctive actions that enable the group to complete complex tasks that a single insect could not accomplish.

(Rephrased for clarity and improved sentence structure)

Revised Answer (140 words):

Swarm intelligence involves insects living in large groups, with each individual insect performing simple instinctive actions that enable the group to complete complex tasks that a single insect could not accomplish. The professor illustrates this concept using ants as an example, demonstrating how they overcome obstacles to obtain food. For instance, when ants encounter a wide gap between branches while foraging on a tree, they form a bridge by connecting their bodies. One ant walks forward and stretches its body, while the next ant walks across the first ant's body and holds on. This process continues until enough ants form a bridge, allowing the rest of the ants to cross the gap and reach the food. This example effectively demonstrates swarm intelligence, showcasing how individual ants contribute to solving complex problems as a collective group.
