Read the following text and answer the questions B

Chawla was born in Karnal, India. She completed her earlier schooling at Tagore Baal Niketan Senior Secondary School, Karnal. She is the first Indian-born woman and the second person in space from this subcontinent. After graduating in Aeroriautical Engineering from Punjab Engineering College, India, in 1982, Chawla moved to the United States the same year. She obtained her Master's degree in Aerospace Engineering from the University of Texas in 1984. Later she did her Ph.D. in Aerospace Engineering in 1988 from the University of Colorado. Determined to become an astronaut even in the face of the Challenger disaster 1986 that broke apart after 73 seconds into flight, leading to the deaths of its seven crew members, Chawla joined NASA in 1988. She began working as a Vice President where she did Computational Fluid Dynamics (CFD) research on vertical take-off and landing. In 1991 she got U.S. citizenship and started her career as a NASA astronaut in 1995. She was selected for her first flight in 1996. She spoke the following words while travelling if the weightlessness of space, "You are just your intelligence.". She had travelled 10.67 million miles, as many as 252 times around the earth.

Her first space mission (Mission STS 87) began on 19 November 1997 with six other astronauts on the Space Shuttle Columbia. On her first mission that lasted for 15 days 16 hours, 34 minutes and 4 seconds, she travelled 6-5 million miles. She was responsible for deploying the Spartan Satellite which however malfunctioned, necessitating a spacewalk by Winston Scott and Tako Doi, two of her fellow astronauts, to retrieve the satellite.

In 2000 she was selected for her second space mission STS 107. This mission was repeatedly delayed due to scheduling conflicts and technical problems. On 16 January 2003, Kalpana Chawla started her new mission with six other space crew on the ill-fated space shuttle Columbia. She was one of the mission spaecialists. Chawla's responsibilities included the microgravity experiments, for which the crew conducted nearly 80 experiments studying earth and space science, advanced technology development, and astronaut health and safety.

After a 16 day scientific mission in space, on I February 2003, Columbia disintegrated over Texas during its re-entry into the Earth's atmosphere. All the crew in Columbia including Chawla died only 16 minutes prior to their scheduled landing. Investigation shows that this fatal accident happened due to a damage in one of Columbia's Columbia's wings caused by a piece of insulating foa foam from the enternal fuel tank peeling off during the lunch. During the intense heat of re- entry, hot gases penetrated the interior of the wing, destroying the support structure and causing the rest of the shuttle to break down.

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.
