Read the following passage and answer the questions B

Valentina Tereshkova was born in a village, in central Russia on 6 March 1937. Her father was a tractor driver and her mother worked in a textile plant. At the age of eight, she began her schooling but did not enjoy it much. She left the school within a few years. Afterwards she completed her education through distance learning. She became interested in parachuting from a young age, and trained in skydiving at the local Aeroclub, making her first jump at age 22 on 21 May 1959. It was her expertise in skydiving that led to her selection as a cosmonaut. After the flight of Yuri Gagarin, the first human being to travel to outer space in April 1961, the Soviet Union decided to send a woman in space. On 16 February 1962, "Proletaria" Valentina Tereshkova was selected for this project from among more than four hundred applicants. Tereshkova had to undergo a series of training that included weightless flights, isolation tests, centrifuge tests, rocket theory, spacecraft engineering, 120 parachute jumps and pilot training in MiG-15UTI jet fighters.

Since the successful launch of the spacecraft Vostok-5 on 14 June 1963, Tereshkova began preparing for her own flight. On the morning of 16 June 1963, Tereshkova and her back-up cosmonaut Solovyova were dressed in space-suits and taken to the space shuttle launch pad by a bus. After completing her communication and life support checks, she was seated inside Vostok-6. Finishing a two-hour countdown, Vostok-6 launched faultlessly.

Although Tereshkova experienced nausea and physical discomfort for much of the flight, she orbited the earth 48 times and spent almost three days in space. With a single flight, she logged more flight time than the combined times of all American astronauts who had flown before that date. Tereshkova also maintained a flight log and took photographs of the horizon, which were later used to identify aerosol layers within the atmosphere.

Vostok-6 was the final Vostok flight and was launched two days after Vostok-5, which carried valary Bykovsky into a similar orbit for five days, landing three hours after Tereshkova. The two vessels approached each other with 5 kilometers at one point, and from space Tereshkova communicated with Bykovsky and the Soviet leader Khrushchev by radio.

Answer the following questions:

উত্তরঃ

Most rivers in our country are in a deplorable condition, with many being polluted, dying, or already dead.

---

The passage highlights that the rivers in Bangladesh are generally "not in good shape," with several already succumbing to death and others in critical condition. This severe degradation is primarily due to extensive pollution, as exemplified by the Buriganga River. The text points out that huge quantities of toxic chemicals and wastes from various sources such as mills, factories, hospitals, clinics, and households are regularly dumped into the rivers. Specifically, Dhaka city contributes significantly to this pollution by discharging thousands of tons of solid waste and highly toxic tannery waste into the Buriganga daily, transforming it into a dying river characterized by polluted water and a persistent foul smell. This indicates a dire environmental crisis impacting the country's crucial river systems.

উত্তরঃ

The river Buriganga held significant commercial value as it played a crucial role in supporting trade and commerce, particularly during the time when the Mughals founded Jahangirnagar (Dhaka) on its banks.

Historically, the river served as a vital waterway, enabling the transport of goods and people. Its navigability facilitated commercial activities, allowing merchants to move products to and from the region, which was instrumental in establishing Jahangirnagar as a thriving economic center.

উত্তরঃ

The Buriganga is described as a dying river primarily due to severe pollution that has drastically degraded its water quality and ecological health. Its once glorious state has been completely reversed by rampant human activities.

According to the provided passage, the river's water is heavily polluted, and a constant foul smell permeates the air around it. This decline is attributed to the daily dumping of massive quantities of toxic chemicals and wastes from various sources. These include mills, factories, hospitals, clinics, households, and other establishments located in and around Dhaka.

More specifically, the city of Dhaka alone discharges about 4500 tons of solid waste into the Buriganga daily. Furthermore, the Department of the Environment (DOE) reports that 20,000 tons of highly toxic tannery waste are released into the river every day. Experts have identified nine major industrial areas, such as Tongi, Tejgaon, Hazaribagh, Tarabo, Narayanganj, Savar, Gazipur, Dhaka Export Processing Zone and Ghorashal, as primary contributors to this catastrophic pollution, effectively sucking the life out of the river that once supported the capital.

উত্তরঃ The Buriganga is polluted by huge quantities of toxic chemicals and wastes from mills, factories, hospitals, clinics, households, and other establishments, along with solid waste from Dhaka city and vast amounts of tannery waste.

---

The Buriganga River is severely polluted by a multitude of sources, as detailed in the passage. Huge quantities of toxic chemicals and various wastes are dumped into the river daily from mills, factories, hospitals, clinics, households, and other establishments. The city of Dhaka plays a significant role in this pollution by discharging approximately 4500 tons of solid waste into the river every day. Moreover, the Department of the Environment (DOE) reports that a staggering 20,000 tons of tannery waste, which includes highly toxic materials, are released into the river daily. Experts have identified nine industrial areas in and around the capital city—Tongi, Tejgaon, Hazaribagh, Tarabo, Narayanganj, Savar, Gazipur, Dhaka Export Processing Zone, and Ghorashal—as the primary contributors to this extensive river pollution, gradually "sucking life out of it."

উত্তরঃ

The Mughals marvelled at the tide level of the Buriganga. As an outcome, they founded their capital Jahangirnagar on its banks in 1610.

---

The Mughals, known for their strategic acumen, were highly impressed by the consistent and significant tide level of the Buriganga River. This natural phenomenon was vital for several reasons: it facilitated easy navigation for large boats, which was crucial for trade and commerce, and it also offered a natural defense mechanism. Recognizing these immense benefits, the Mughals chose the banks of the Buriganga to establish their new capital, Jahangirnagar, in 1610. This strategic decision leveraged the river's resources for transportation, drinking water, and economic activities, contributing significantly to the city's growth and prosperity, eventually leading to its renaming as Dhaka and its development into a heavily populated metropolis.
