Answer the following questions.
a. What is a hyperloop? How does it work?
A projected train called the Hyperloop would be able to go at amazing speeds. Because it is contained in a tube with no air within, it moves extremely quickly. There won’t be any friction to cause the train to slow down because of the absence of air.
b. How is hyperloop more beneficial than traditional trains?
Compared to conventional or high-speed rail, hyperloop is significantly more advantageous and better. Because the track doesn’t have to continually supply electricity to the pods and because the pods may depart every 30 seconds, it is less costly and consumes less energy.
c. Does the hyperloop have a successful history? How?
Since the initial idea for the hyperloop was to utilize waggons and pneumatic tubes to transfer mail and packages between buildings, the answer is no, it has not had a successful history.
d. Write the contributions of Robert Goddard and Elon Musk for the development of the hyperloop.
Elon Musk, the creator of Space X and Tesla, came up with the concept of the hyperloop to offer extremely quick intercity transportation. Elon sees a “fifth mode” of transportation that uses travel pods contained within steel tubes in addition to cars, airplanes, boats, and trains. With his “Hyperloop Alpha” article published in August 2013, he rekindled interest in the concept of the hyperloop.
Robert Goddard’s early 20th-century “vactrain” concept is unmistakably a forerunner of the hyperloop. Numerous notions that are similar to that have since been put forth.
e. What relation does speed have with air resistance? Explain.
A moving body’s speed is reduced by air resistance, and the opposite is also true. The speed will significantly increase because there won’t be any air resistance because the Hyperloop will go via vacuum tubes.
f. What are hyperloop capsules compared with? How are they similar?
Because both Hyperloop and Boeing 747 accelerate at the same measure of acceleration, Hyperloop capsules are likened to Boeing 747.
g. How do the passengers feel while travelling via the hyperloop? What will be done to make it luxurious?
The hyperloop ride is similar to taking an elevator or flying in a plane in terms of how passengers feel. Each passenger gets access to a personal entertainment system and the cabin offers lovely views of the outside, ensuring a comfortable flight.
h. Why does the writer doubt the success of Hyperloop? What does success depend on?
The destinations, the regional economy, and the geographic area will all have an impact on how well hyperloop works. Because of the massive multibillion-dollar investment and the fact that the projects are still in the pilot and experimental stages, the author has doubts about the hyperloop’s practicality. Due to inaction from the government, Nikola Tesla and Elon Musk had already shut down the identical idea initiative.
Critical Thinking
a. Is the hyperloop the future of transportation or just a dream? What do you think? Justify your opinion with suitable reasons.
Basically, Hyperloop is a conceptual transport system in which passengers are loaded into pods and fired through vacuum tubes all at a supersonic speed. Hyperloop isn’t just about speed; it also aims to be environmentally friendly.
Similar to the Hyperloop, the idea is not brand-new. In the 19th century, pneumatic tubes for transferring packages, mail, and money gained popular recognition; they are still in use today at grocery stores, post offices, and financial institutions. The idea behind the hyperloop is similar to pneumatic postal delivery systems. In the past, even flying by air seemed inconceivable, yet today, we frequently travel by air. No one can thus assert that anything is impossible because everything that was once only a dream has become a reality.
In conclusion, it is clear that the Hyperloop may shape future global transportation infrastructure. Even though it is not anticipated to happen for decades, it will have a significant influence on everyday people’s lives if it does. In addition to comfort and environmental benefits, we can also wish for financial success.
However, new technologies take time to develop, so it will be some time before we can ride in a pod within a sealed tube with a sound no louder than a mild “SWOOSH.”
b. The number of private vehicles is increasing day by day in Nepal beyond the capacity of our infrastructure. What do you think should be done to curb the ever-growing number of private vehicles? Discuss.
In Nepal, the number of private automobiles is growing at a rate that is faster than the country’s infrastructure can keep up with. The percentage of Nepalese people who drive their own automobiles is rising gradually. Although technology makes their daily lives easier, it also has a significant negative impact on the environment. Since the extensive use of private automobiles harms the environment and boosts the emissions of dangerous gases that may cause serious issues in the future, they should be outlawed. Some safety precautions had to be taken in order to control this dangerous situation.
Dissuading individuals from choosing to purchase autos is the best course of action. By raising the cost of automobile tolls and creating a system of progressive car taxes, this may be accomplished successfully. A cap on the maximum number of vehicles any family may possess may be imposed by the system, and the tax rate applicable to each vehicle may rise as more vehicles are purchased.
However, unless more steps are taken to improve Nepal’s appalling public transportation infrastructure, all efforts will be for nought. During rush hour, additional buses must run, and those already running must be improved for comfort (more cushions, air conditioning, better suspension, etc.). It is necessary to sustain the regularity and dependability of public transportation networks. When maintaining bus and train terminals, cleanliness and hygiene must be taken into consideration.
Along with the aforementioned strategies, work must be done to dispel the myth that taking public transportation is deplorable. The most effective defence against this is to make public transportation as respectable and enjoyable as possible.

Corrected Passage
Within the state of Arizona, Rob, along with his family, moves frequently from city to city. After his arrival, one of his first tasks was to find an apartment close to work, as he did not have a car. Usually, there are many different places to choose from, and he considers cost, location, and luxury. If one apartment has a washing machine and dryer and costs four hundred dollars a month, he prefers to rent it over another apartment which has significantly less rent and is located two blocks from a Laundromat. Rob’s family never wanted to live in an apartment on the thirteenth floor, since all of them fear heights. He also tried to choose an apartment with a landlord recommended by former tenants. Everybody knows that it is important to find a responsible landlord. Rob and his wife love to cook together when both are free, so they need a spacious, well-equipped kitchen. Rob often looks for a place with an air conditioner because there are so many scorching days and nights in Arizona. Whenever Rob finds a new apartment, all of his concerns disappear. He felt relieved and called his mother. Someone understands!
