Dreams have fascinated philosophers for thousands of years, but only recently have dreams been subjected to empirical research and scientific study. Chances are that you've often found yourself puzzling over the content of a dream, or perhaps you have wondered why you dream at all.

Frist, let's start by answering a basic question: What is a dream? A dream can include any of the images, thoughts and emotions that are experienced during sleep. Dreams can be Extraordinarily vivid or very vague; filled with joyful emotions or frightening images; focused and understandable or unclear and confusing.
Why do we dream? What purpose do dream serve? While many theories have been proposed about the reason and function of dream, no consensus has emerged. Considering the time we spend in a dreaming state, the fact that researchers do not yet understand the purpose of dreams may seem baffling. However, it is important to consider that science is still unravelling the exact purpose and function of sleep itself. Some researchers suggest that dreams serve no real purpose, while others believe that dreaming is essential to mental, emotional and physical well-being. Next, lets learn more about some of the most prominent dream theories. Consistent with the psychoanalytic perspective, Sigmund Freud's theory of dreams suggests that dreams are a representation of unconscious desires, thoughts and motivations. According to Freud, people are driven by aggressive and sexual instincts that are repressed from conscious awareness. While these thoughts are not consciously expressed, they find their way into our awareness via dreams. In his famous book, the Interpretation of Dreams, Freud wrote that dreams are ".......disguised fulfillments of repressed wishes."

 

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.
