h. Why is the author disturbed by the thought of the creatures like the nudibranch and medusa?
Thoughts of nudibranchs and medusas frighten the author, conjuring up strange and strange images similar to those in a dream for him.
i. What does the writer mean by “they remind me of the whole earth at once?"
Using the phrase "they remind me of the whole earth at once," the writer is implying that it is very difficult and odd to explain the link between and among life and nonliving objects. A person's confusion grows as he or she attempts to comprehend.
a. How does the author make satire on the modern idea of the 'self' based on individuality, independence and uniqueness?
In this article, Lewis Thomas' "Medusa and the Snail" mocks our contemporary concept of "self," which emphasizes the importance of being one's own person, having one's own identity, and being distinct from others.
Once an adult jellyfish swallows a small freshly born slug, the slug slowly eats away at the jellyfish until the jellyfish is reduced to a spherical parasite attached to the snail's skin near its mouth and eventually eaten away completely. It is finally eaten until it is reduced in size and the jellyfish is depleted of its essence, which causes the snail to expand.
This narrative demonstrates that both species are unable to survive on their own, and must rely on one other for existence. Using the story of the nudibranch and the medusa, the author demonstrates the importance of living in harmony with one another and working together.
Friendship and reliance on one other for life and existence are also shown in the tale. In this way, the author argues that current pride in one's own distinctiveness, liberty, and originality isn't grounded in reality.
b. Analyze the essay as a creative defense of the interdependence observed in the ecosystem.
The Medusa and the Snail" by Lewis Thomas is a creative way to show how ecological interdependence works. The jellyfish and snail in the Bay of Naples are linked by their need for each other to live and stay alive. This shows how intertwined the environment is.
In this essay, we saw two species in the Bay of Naples that are very close to each other. Their dependence on each other not only explains why they live, but also how the ecosystem can stay balanced.
There are a lot of different ways humans and animals connect to each other, as well as how they get along with each other and the rules of their community. As well, it makes people realize that they're not the only ones who want to improve their mental and emotional health.
When people work together on a project, they build a sense of community and belonging. This is true both on a personal and a social level. It also says that ecosystems are very important for the protection and preservation of living and non-living things or animals, as well as plants.
a. Write a 250-word essay on "Independence vs. Interdependence"
An Essay on Individualism vs. Socialism
There are usually two ways that people think about themselves and their relationships with other people. To begin with, an individual's perception of his or her existence is that he or she exists independently of others is known as the autonomous self-concept. Interdependent self-concept is characterized by a person's sense of belonging to a larger community. Both the notions of independence and dependency have advantages and disadvantages.
Interdependence self-concept is based on the idea that people in a community rely on each other for existence and growth. To further implant the concept that mental growth and development is not a solitary endeavor, it provides social support for one another's progress as well. Responsibility for sharing is promoted by encouraging people to assume diverse responsibilities that contribute to society's progress and development. Fear may be overcome if you have a strong sense of self-reliance.
In addition, it fosters a sense of community and a sense of belonging among those involved, whether on a personal or professional level. Independent self-concept is concerned with what makes a person stand apart from the rest of society in terms of his or her internal traits. Because of this, one feels better about himself or herself, which makes it easier on family, friends, and the rest of society. More so, if independence is a goal, it boosts one's self-worth and self-esteem.
Individualism increases one's self-confidence, but interdependence focuses on how individuals interact with one other and how society's current rules govern how people interact. As a whole, society and the country benefit much from both Dependency: To acquire what one desires, one is reliant on the efforts of others. in the person of (you) As a result of one's own hard work, one is able to achieve one's goals.

B. Write a newspaper article highlighting the increasing individualism in the modern Nepali society.
Modern Nepalese society is becoming more individualistic. Individualism is defined as the power we have as individuals to do what we want. We would have a more cohesive society if everyone was free to follow their own ambitions. Individualism is becoming more prevalent in Nepalese culture.
Individualism places a high value on self-determination and self-actualization. A culture of individualism places a high value on the accomplishments of those who have made a significant contribution to society.
Nepalese culture now places a high priority on individualism. However, it should be construed positively rather than negatively. Individualism has certain advantages, including the ability to make one's own decisions. Male or female, a number of groups are attempting to provide every citizen their own unique identity.
Support for gender equality in the workplace, income, education, and political leadership is strongly linked to this kind of behavior. Female employment and educational achievement and lower fertility rates are also linked to individualism.
