AVICII’S LIFE AFTER REHAB

Once he completed his month in rehab, Avicii seemed to have a new outlook on life. He was meditating regularly, reading about the collective unconscious, and got a puppy. After not performing for a long period of time, he returned to the stage in 2016 at Miami’s Ultra Music Festival. It was announced a few days after this gig that he would not be performing live anymore. Avicii chose to not perform so that he could focus on bettering his mental health.

Despite appearing to have new-found stability, Avicii still struggled to deal with his mental health issues. While continuing to suppress the anxiety and depression that he frequently felt, Avicii also started to become disinterested in his music career. During this time, he was smoking and drinking on occasion which may have resulted in a resurgence of his disassociation feelings.

He told Tereza Kacerova, his girlfriend at the time, “What if everyone around me is just a projection in my mind? Sometimes I just think these things. About how nothing really matters.”

Avicii started to focus heavily on meditation which he found to be helpful in clearing the “nonsense” from his mind. He believed that a deep form of meditation taught by Maharishi Mahesh Yogi was a way to exercise his brain which he had decided would lead to his happiness. Despite this form of meditation typically being done in 20 minutes increments, Avicii would sometimes spend full days meditating in an attempt to reach enlightenment faster.

What can be inferred about Avicii's mental state after rehab?

Read the following passage about the The Importance of Social Media in Modern Society and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

In the 21st century, social media has become a crucial element of everyday life[I]. Platforms such as Facebook, Twitter, Instagram, and TikTok link individuals around the world, [IV]. Although some may critique social media for promoting negativity, it is important to acknowledge its numerous positive effects on society[III]. This essay will delve into the importance of social media, its influence on shaping public perception, and the challenges it poses.[II]

One of the primary benefits of social media is its ability to foster communication and connection. People can maintain relationships with friends and family, regardless of geographical barriers. This aspect is particularly vital for those who live far away from loved ones. For example, a student studying abroad can easily share their experiences with family through posts, photos, and video calls. Furthermore, social media enables individuals to connect with like-minded people and build communities around shared interests or causes. Activist groups, for instance, often use social media platforms to rally support for important issues, raising awareness and mobilizing action more efficiently than traditional methods.

Moreover, social media serves as a powerful tool for information dissemination. News spreads rapidly through these platforms, allowing individuals to stay informed about current events. During emergencies, such as natural disasters, social media can provide crucial information in real time, helping people stay safe and informed. However, this rapid dissemination of information also raises concerns about the accuracy and reliability of the content being shared. Misinformation can spread just as quickly as legitimate news, leading to confusion and mistrust.

Despite the challenges posed by misinformation, social media plays a significant role in shaping public opinion. People often turn to these platforms to voice their opinions and engage in discussions on various topics. For instance, political debates and social movements frequently gain traction through social media, allowing individuals to express their views and influence others. This democratization of discourse can empower marginalized voices and facilitate social change. However, it is crucial to approach online discussions critically, as echo chambers can form, reinforcing existing beliefs rather than encouraging open dialogue.

In conclusion, while social media presents challenges such as misinformation and polarized discussions, its positive contributions to communication, information dissemination, and social activism cannot be overlooked. As society continues to evolve, it is essential to harness the potential of social media while being mindful of its pitfalls. By promoting responsible use and critical thinking, we can maximize the benefits of social media and foster a more connected and informed society.

Mệnh đề nào sau đây đúng?

Một người đi xe máy từ nhà (vị trí A) đến nơi làm việc (vị trí C). Do cần phải đổ xăng nên người đó đi tới trạm xăng (vị trí B) rồi mới đến nơi làm việc. Biết khoảng cách từ nhà đến trạm xăng là 1 km, và từ trạm xăng tới nơi làm việc là 1 km. Vị trí của nhà, trạm xăng và nơi làm việc được biểu diễn trên hình vẽ. Tính quãng đường người đó đã đi và độ dịch chuyển của người đó.

Quãng đường đi được của người đó là $s=$ km.

Vì tam giác ABC là tam giác vuông, nên độ lớn của độ dịch chuyển $\overrightarrow{AC}$ của người đó là

$d=AC=\sqrt{AB^2+BC^2}\simeq$ km (kết quả là số thập phân có 1 chữ số sau dấu phẩy).

Vì tam giác ABC là tam giác vuông cân nên $\widehat{CAB}=45^o$.
