Do they have kids shampoo for toddlers? Down in cotton? Yeah, so we like finding new shampoo for kids to have kids shampoo for kids. We gonna use stuff like down in cotton, Earth Mama, Gildan, River, G., brands. So, we gonna have some kids shampoo for kids. So, we got a little cash and see where we could get that stuff. Where we can get that shampoo for kids to shave. So, we go to Dollar General. So, I'mVisual update for Ethan. That haircut is CURLED terminates in solid style. Here we are with our made up CURLED terminates a kids haircut. So, Ethan, what do you think about your new haircut? And Ethan, are you giving your haircut to Ethan today or not? Ethan, like I just cut your hair. Let's go. Now, why did I cut your hair? Like I just wanted to experiment my new haircut. Who's shaving your hair? Who's cutting your hair? Yo!. 1 . The theory of continental drift, proposed by Alfred Wegener, suggests that the continents were once joined together in a supercontinent and have subsequently drifted apart over millions of years. This theory explains the similarities in the shapes of coastlines on opposite sides of oceans and the presence of identical fossils on different continents. However, some scientists initially rejected Wegener's theory due to the lack of a convincing explanation for the driving force behind continental drift. In the 1960s, the theory of plate tectonics emerged, providing a more comprehensive understanding of Earth's dynamic surface. Which of the following statements is NOT consistent with the theory of plate tectonics? a) The Earth's crust is divided into several plates that move over the Earth's mantle. b) Convection currents in the mantle drive the movement of the plates. c) The collision of plates can lead to the formation of mountain ranges and earthquakes. d) The continents are fixed in their positions and do not move over time. 2. In astronomy, what is the name of the imaginary boundary surrounding a black hole from which nothing, not even light, can escape? a) Event horizon b) Oort cloud c) Kuiper belt d) Hubble sphere
3 . The field of psychology delves into the complex workings of the human mind, exploring our thoughts, emotions, and behaviors. One influential theory in psychology is the humanistic perspective, which emphasizes the importance of individual growth, self- actualization, and free will. Which of the following psychologists is considered a prominent figure in the humanistic psychology movement? a) B.F. Skinner b) Carl Rogers c) Sigmund Freud d) Albert Bandura 4 . As the use of social media platforms continues to grow exponentially, the potential for their influence on individuals and society as a whole becomes increasingly significant. While these platforms offer valuable tools for communication and connection, concerns have also emerged regarding their potential for manipulation, misinformation, and addiction. What is the most effective approach to addressing the negative impacts of social media while maximizing its positive potential? a) Increased government regulation and censorship of social media content. b) Development of individual self-awareness and critical thinking skills to navigate social media responsibly. c) Collaboration between social media platforms, researchers, and policymakers to develop ethical guidelines and best practices. d) A combination of all of the above, tailored to the specific context and challenges of each platform. 5 The field of artificial intelligence (AI) has made significant advancements in recent years, impacting various aspects of our lives. AI algorithms are increasingly being used in
decision-making processes, raising ethical concerns about potential bias and discrimination. What is the primary challenge associated with ensuring fairness and ethical considerations in AI development and implementation? a) Lack of adequate data to train AI models. b) Technical limitations in achieving perfect accuracy. c) Difficulty in eliminating human biases from algorithms. d) Concerns about job displacement caused by automation. 6. Which of the following is a type of investment fraud? a) Ponzi scheme b) Pump-and-dump scheme c) Pyramid scheme d) All of the above 7. What is mutation testing and how does it differ from code coverage? a) Seed faults to test detection - complements line coverage metrics. b) Test cross-browser compatibility - unrelated to code coverage. c) Fuzz testing by adding random mutations - mostly redundant to coverage. d) Confirm code is unchanged between builds - differs from coverage metrics. 8 . The Black-Scholes model is a mathematical formula used to calculate the theoretical price of options contracts. This model is based on several assumptions, including constant volatility and risk-free interest rates. What is the primary limitation of the Black-Scholes model? a) It only applies to European-style options.

b) It requires accurate estimates of future volatility. c) It is computationally complex to implement. d) It does not account for market frictions. 9. What are the differences between software development life cycle (SDLC) models like Waterfall, Agile, Spiral? a) Waterfall is sequential, Agile iterative, Spiral risk-based - must match methodology to needs. b) All models are identical. c) Agile is always the optimal approach. d) Models relate to personnel only, not software process. 10. How does public key cryptography work and what is the significance of trapdoor functions? a) Uses key pairs for encryption/decryption, trapdoor functions enable one-way easy but difficult inverse operations. b) Symmetric system where both parties share the same private key. c) Requires exchange of multiple interdependent randomized public keys. d) Relies on easily factorable prime numbers for encryption. 11 . The term "financial leverage" refers to the use of borrowed funds to increase potential returns. While leverage can magnify profits, it can also amplify losses. What is the primary risk associated with using financial leverage? a) Increased interest rates b) Decreased liquidity c) Market fluctuations d) All of the above
12. What is deadlock in concurrency and what are some ways it can be prevented or mitigated? a) Two or more competing actions waiting for resources held by the other - can be avoided by ordering, detection, and process design. b) Infinite loop caused by programming error. c) Terminal system crash or halt from which recovery is impossible. d) Algorithm exhibiting exponential complexity as inputs grow. 13. Who is often considered the father of modern philosophy and famously said, "I think, therefore I am"? a) Aristotle b) Immanuel Kant c) John Locke d) René Descartes
