Introduction: Artificial Intelligence (AI) is one of the most revolutionary technologies of our time, shaping industries, economies, and even personal lives. While some view AI as a groundbreaking tool that enhances human capabilities, others fear its potential risks, such as job displacement, ethical concerns, and security threats. This conce essay argues that AI is more of an opportunity than a threat, despite the challenges it presents. 

Al as an Opportunity: Firstly, AI enhances efficiency and productivity. AI-driven automation significantly improves efficiency in various industries by handling repetitive and time-consuming tasks. In sectors like healthcare, Al-powered diagnostic tools help doctors detect diseases more accurately, while in manufacturing, automation reduces human errors and increases output. This allows businesses to operate more efficiently, ultimately benefiting society. 

Secondly, AI drives innovation and ecoc growth. Al has fueled advancements in various fields, including medicine, education, and space exploration. Al-powered robots assist in complex surgeries, personalized learning platforms enhance education, and intelligent algorithms help scientists make  groundbreaking discoveries. Moreover, AI has created new job opportunities in tech industries, leading to economic growth. 

Thirdly, AI improves decision-making and problem-solving.  Al systems can process vast amounts of data faster and more accurately  than  humans. This capability allows businesses and governments to make informed decisions. For instance, AI is used in climate modeling to predict natural disasters and in cybersecurity to detect threats before they cause harm. These applications demonstrate Al's ability to address global challenges effectively. 

Counter-Argument: AI as a Threat 

Despite its benefits, AI does pose certain risks. One major concern is job displacement due to automation. Many fear that AI-driven machines will replace human workers, leading to unemployment in sectors like manufacturing, transportation, and customer service. Additionally, ethical concerns arise regarding data privacy, bias in Al decision-making, and the potential misuse of Al in warfare or surveillance. 

Conclusion: While AI presents some challenges, its potential to improve human lives far outweighs the risks. The key to ensuring AI remains an opportunity rather than a threat lies in responsible development, ethical regulations, and workforce adaptation. If managed correctly, AI can lead to a future where technology complements human intelligence, fostering innovation and progress.

প্রশ্নে বলা হচ্ছে, একটা বাস 60 জন যাত্রী নিয়ে যাত্রা শুরু করে। যখন ১ম Stop-এ আসে তখন x জন যাত্রী নেমে যায় এবং ৪ জন্য যাত্রী উঠে। ২য় Stop-এ এসে $\frac{1}{3}$  অংশ নেমে যায় এবং 5 জন যাত্রী উঠে। যদি বর্তমানে 37 জন যাত্রী থাকে তাহলে ১ম Stop-এ কতজন যাত্রী নেমেছিল তা বের করতে হবে। 

As in the second stop $\frac{1}{3}$  passenger get off from the bus. So total passenger left $\frac{2}{3}$ in the bus. 

According to question, 

$(60 - x + 8) \times \frac{2}{3} + 5 = 37$ 

$\Rightarrow (60 - x + 8) \times \frac{2}{3} = 37 - 5$

$\Rightarrow (68 - x) \times \frac{2}{3}= 32$

$\Rightarrow (68 - x) = 32 \times \frac{2}{3}$

⇒ 68 - x = 48 

⇒ - x = 48 - 68 

⇒ - x = - 20 

$\therefore$ x = 20 

ans: 20.
