Summary of roadside stand by Robert Frost?

User Avatar

Asked by Wiki User

In this poem, the poet contrasts the lives of poor and deprived countryside people who struggle to live with the thoughtless city people who don't even bother to notice the roadside stand that these people have put up to sell their goodies.

The poem starts with the description of the roadside stand and the intention behind it. A small time farmer builds a vegetable stand at the edge of the highway outside his house in the hope that passing cars would buy the produce and earn a bit of the money that supports cities from falling into ruin. He only wants to earn a living, he is not begging for money.

However, no cars ever stop and the ones that even glance in the direction cof the stand without any feeling of compassion or relatedness (out of sorts) only comment about how the construction spoils the view of the surroundings or how badly painted the wrongly pointed North and South signs are or to notice without interest the wild berries and squash for sale in the stand or the beautiful mountain scene.

The farmer tells the rich travelers to keep their money if they meant to be mean and that the hurt to the view is not as important as the sorrow he feels on being ignored. He only wishes for some (city) money so that he may experience the plush life (make our beings expand) portrayed by the movies and other media, which the political parties are said to be refusing him.

Frost goes on to say that even though these people have benefactors (good-doers), who plan to relocate them in villages where they can have easy access to the cinema and the store, they are actually selfish ('greedy good-doers' and 'beasts of prey') and only help these "pitiful kin" to indirectly advantage themselves. The altruists wish to make these villagers completely dependent on them for all their benefits and comforts, thus robbing them of the ability to think for themselves and be independent. 'The ancient way' could mean the old way when people worked during the day and slept at night. This is being reversed by the new 'greedy good doers' who teach these people to not use their brain. They are unable to sleep at night because they haven't worked during day time or because they are troubled by their new lifestyle.

Frost then talks about his personal feelings, saying that he can hardly breathe thought of the farmer's dashed hopes. The open windows of the farmer's house seem to wait all day just to hear the sound of a car stopping to make a purchase. However they are always disappointed, as vehicles only stop to inquire the price, to ask their way ahead, to reverse or ask for a gallon of gas.

According to the poet, the progress required has not been found by these country folk ("the requisite lift of spirit"). Their lifestyles provide ample evidence to support this fact. He sometimes feels that it might be best to simply put these people out of their pain and hardships of existence. However, once rational thinking returns to his mind, he wonders how HE would feel if someone offered to do him this supposed service.

Who invented the lamb?

User Avatar

Asked by Wiki User

It is believed that sheep were domesticated around 10,000 years ago in the Fertile Crescent region of Mesopotamia. The exact person or group responsible for "inventing" the lamb is unknown, as domestication happened gradually over generations through human interaction with wild sheep. Domestication likely occurred for their meat, wool, and other resources.

What is the relationship between evolution and geography?

User Avatar

Asked by Wiki User

Geography can influence evolution by creating barriers that limit the movement of species, leading to genetic isolation and potentially the development of new species through natural selection. Different environments can also drive adaptation in species, with variations in geography providing diverse ecological niches for the evolution of different traits.

Evolution of operating system?

User Avatar

Asked by Wiki User

The journey of operating systems (OS) evolution is a compelling narrative of how software has evolved to efficiently manage hardware resources while continually enhancing user interaction over the decades. In the embryonic stages during the 1950s and 1960s, operating systems were fairly rudimentary, tailored specifically for particular hardware, and primarily served as basic system managers. They provided a rudimentary interface for programmers to interact with the machine, a far cry from the sophisticated user interfaces we see today. As we transitioned into the late 1960s and early 1970s, the advent of batch processing emerged as a significant milestone, enabling the execution of jobs without the need for manual intervention. Simultaneously, the concept of multiprogramming began to take root, allowing multiple programs to reside in memory and share CPU time, significantly improving system utilization.

With the 1970s came the era of time-sharing systems, a groundbreaking innovation that allowed multiple users to interact with the computer simultaneously, bringing a semblance of multitasking. This era also saw the advent of real-time operating systems, engineered to meet the stringent timing constraints of specific applications. The late 1970s and 1980s heralded the personal computing era, where operating systems like MS-DOS, Windows, MacOS, and various Unix/Linux distributions became the cornerstone of the burgeoning personal computer market. They introduced user-friendly interfaces and a broad spectrum of functionalities, democratizing computer access. As we sailed into the 1980s and 1990s, networking capabilities became an integral part of operating systems, paving the way for distributed operating systems that could harness the collective power of interconnected computers to accomplish tasks.

The late 1990s and 2000s saw the internet's explosion, which significantly influenced operating system development, enhancing networking features, security, and support for web-based applications. It was during the 2000s and the 2010s that mobile operating systems like Android and iOS emerged with the rise of smartphones, optimized for power efficiency, connectivity, and touch interfaces, redefining how individuals interacted with digital technology. The 2010s also marked the era of cloud computing and virtualization, where modern operating systems evolved to support efficient resource utilization and isolation of applications through virtual machines and containers.

Now, as we venture into the late 2010s and 2020s, operating systems are being fine-tuned for IoT (Internet of Things) devices and edge computing, with a focus on lightweight, secure, and efficient operations to cater to the diverse requirements of modern-day computing environments. The burgeoning integration of AI (Artificial Intelligence) and machine learning into operating systems is enabling smarter, context-aware, and adaptive system behaviors, marking a significant stride towards more intelligent and autonomous systems. Security, in response to escalating cyber threats, is becoming a pivotal focus in modern OS design, with a security-first approach being adopted to provide robust protection against a myriad of cyber threats.

The relentless innovation in the realm of operating systems over the decades underscores the dynamic nature of the computing domain. From being mere facilitators of hardware-software interaction, operating systems have transitioned to being central linchpins in a highly interconnected computing ecosystem. They now offer a plethora of services, features, and capabilities that drive modern computing experiences, catering to a diverse range of requirements from personal computing to enterprise-level applications, and everything in between. The continual evolution of operating systems reflects the overarching narrative of technological progress, adapting to meet the ever-changing needs and challenges of the modern digital world.

What provides the direction evolution takes?

User Avatar

Asked by Artist6541001

The direction evolution takes is primarily determined by natural selection. This process favors traits that enhance an organism's survival and reproductive success, causing those traits to become more common in subsequent generations. Additionally, environmental factors play a role in shaping evolution by exerting selective pressures that favor certain adaptations over others.

Why is it difficult to prove that evolution happens?

User Avatar

Asked by Wiki User

Proving that evolution happens can be challenging for a few reasons. Firstly, evolution occurs over long periods of time, making direct observation difficult. Additionally, the process of evolution involves gradual changes in populations, which can be difficult to track and measure. Lastly, the evidence for evolution is primarily based on indirect observations, such as fossil records and genetic analysis, which some skeptics may question.

How monkeys form humans?

User Avatar

Asked by Wiki User

Monkeys do not directly evolve into humans. However, humans and monkeys do share a common ancestor. Over millions of years, evolutionary processes led to the development of different species, with humans evolving separately from monkeys. The evolutionary path that led to modern humans involved significant changes in brain size, tool use, and social behavior.

What occurred to other species when oxygen levels rose on earth?

User Avatar

Asked by Wiki User

When oxygen levels rose on Earth, it resulted in the diversification and expansion of oxygen-dependent organisms, including the development of more complex life forms. This increase in oxygen levels formed the basis for the evolution of aerobic respiration and allowed for the colonization of new ecological niches. However, these changes may have also put pressure on anaerobic organisms, leading to their decline in certain environments.

Does sexual selection lead to violence?

User Avatar

Asked by Wiki User

Sexual selection, which is the process by which certain traits are favored for reproduction, can indeed lead to violence in some species. In some cases, competition over mates can result in aggressive behaviors such as fighting or intimidation. However, it is important to note that not all forms of sexual selection result in violence, and many species have alternative strategies for mate selection that do not involve aggression.
