why aren't volcanoes associated with continent-continent convergence?
Volcanoes are not commonly associated with continent-continent convergence because this type of tectonic boundary typically involves the collision and uplift of continental crust, rather than volcanic activity.
During continent-continent convergence, two continental plates collide, creating immense compressional forces. As the plates collide, the continental crust becomes highly deformed and uplifted, resulting in the formation of mountain ranges, such as the Himalayas. This process is primarily characterized by intense folding, faulting, and crustal thickening.
Volcanic activity, on the other hand, is commonly associated with other tectonic boundaries, such as subduction zones or divergent plate boundaries. Subduction zones occur when one tectonic plate is forced beneath another, leading to the formation of volcanoes due to the melting of the subducted plate and the subsequent rise of magma. Divergent plate boundaries, where plates move away from each other, also give rise to volcanic activity as magma rises to fill the gap created by the spreading plates.
In continent-continent convergence, the collision and compression of continental crust do not typically generate the necessary conditions for the formation of volcanic activity. Instead, the focus is on the deformation and uplift of the crust, resulting in mountain building rather than volcanic eruptions.

The Malaysian Tin mining industry collapsed due to many reasons. Some of them are- competition from other countries, lower demand , inadequate technology, environmental concerns and Government policies.
The Malaysian tin mining industry collapsed due to several factors that contributed to the economic downfall of the industry.
1) Competition from other countries: The global tin market faced stiff competition from other countries like Brazil, Indonesia, Bolivia, and Thailand. These countries had abundant tin reserves, and their mining processes were more efficient than those of Malaysia, making it challenging for Malaysia to compete.
2) Lower demand: The demand for tin had reduced globally due to the development of substitute materials like aluminum, which had similar properties to tin but was cheaper and lighter.
3) Inadequate technology: The Malaysian tin mining industry relied on old and inefficient methods of mining that consumed too much time and resources. Moreover, the industry was characterized by widespread corruption and low productivity, which further reduced the competitiveness of Malaysia's tin production.
4) Environmental concerns: The mining industry in Malaysia had severe environmental consequences, which led to public outcry, forcing the government to impose strict environmental regulations. The regulations, coupled with the high cost of compliance, made it difficult for the mining industry to operate, leading to a decline in production.
5) Government policies: The Malaysian government had over-regulated the mining industry, which stifled innovation and productivity.
Moreover, government policies were inconsistent, and there was a lack of transparency in the regulatory framework. This led to a lack of investor confidence, making it difficult for the industry to attract investments and expand.
Overall, the combination of factors like competition from other countries, lower demand , inadequate technology, environmental concerns and Government policies led to the collapse of the Malaysian tin mining industry, resulting in significant economic losses for the country.

Give a proof by contrapositive. (5 marks)
Rule of Inference used: Disjunctive syllogism.
The conclusion that follows is Tina is smart. Because we know that Tina is not lucky, which means she cannot get a scholarship because she has to be lucky to receive a scholarship. However, Tina is either smart or lucky, and since Tina is not lucky, it is valid to conclude that she is smart.b)Proof by contrapositive:If n and m are integers and n*m are odd, then n and m are odd. We can write this statement in the form of a conditional statement as P → Q where P = n*m are odd, Q = n and m are odd.
The contrapositive of P → Q is ¬Q → ¬P. We have to prove the contrapositive that if n and m are even, then n*m is even. If n and m are even, then we can write n = 2p and m = 2q, where p and q are integers. n*m = 2p * 2q = 4pqSince p and q are integers, the product pq is also an integer, and the product of two even numbers is always even.

Case study on Ethic in Research Find a case study which can be discussed and analysed for ethical considerations in Research and analytics. Give a brief idea of the case in your own words. (200-250 wo
One notable case that can be discussed and analyzed for ethical considerations in research and analytics is the Tuskegee Syphilis Study. This case took place in the United States from 1932 to 1972 and involved the U.S. Public Health Service (PHS) studying the natural progression of untreated syphilis in African American men.
The study initially aimed to provide medical treatment to impoverished African American men in rural Alabama who had contracted syphilis. However, instead of providing them with proper treatment, the PHS researchers misled the participants, withholding information about their diagnosis and the available treatment options. The researchers wanted to observe the long-term effects of syphilis without intervening, which led to the denial of appropriate medical care.
Over the course of the study, the participants were denied penicillin even after its discovery as an effective treatment for syphilis. They were instead given placebos or ineffective treatments, which led to the progression of the disease, severe health complications, and, in some cases, death. The study continued despite the ethical guidelines established over the years, including the Nuremberg Code (1947) and the Declaration of Helsinki (1964), which emphasized the importance of informed consent and the duty to protect human subjects in research.
The Tuskegee Syphilis Study raised numerous ethical concerns. The participants were not adequately informed about the nature of the study, its risks, or the available treatments. Their autonomy and right to make informed decisions about their health were violated. Additionally, the study perpetuated racial disparities and discrimination, as it specifically targeted African American men and perpetuated negative stereotypes about their health.
The Tuskegee Syphilis Study led to significant changes in research ethics and the establishment of guidelines to protect human subjects. It highlighted the importance of informed consent, the need for ethical review boards, and the duty of researchers to prioritize the well-being and rights of participants. The case serves as a poignant reminder of the ethical obligations that researchers and institutions have when conducting studies involving human subjects.

Transportation deregulation is argued to be good for several reasons: Increased Competition, Innovation and Efficiency, Economic Growth and Job Creation, Flexibility and Adaptability and Consumer Benefits. It's important to note that while proponents argue for the benefits of transportation deregulation, critics raise concerns about potential negative impacts such as safety issues, reduced labor protections, and market concentration.
Increased Competition: Deregulation promotes competition by removing barriers and restrictions that limit entry into the transportation market. This leads to increased competition among transportation providers, which can result in lower prices, improved services, and greater efficiency. Consumers can benefit from a wider range of choices and potentially lower transportation costs.
Innovation and Efficiency: Deregulation encourages innovation and efficiency in the transportation industry. Without strict regulations and controls, transportation providers have the freedom to explore new business models, technologies, and operational strategies. This can lead to improved processes, better utilization of resources, and the development of more effective transportation solutions.
Economic Growth and Job Creation: Deregulation can stimulate economic growth and job creation. By removing regulatory barriers, new transportation businesses can enter the market, expand their operations, and create employment opportunities. Additionally, deregulation can attract investment and foster entrepreneurial activity in the transportation sector, contributing to overall economic development.
Flexibility and Adaptability: Deregulation allows for greater flexibility and adaptability in responding to market demands and changing customer needs. Transportation providers can adjust their services, routes, pricing, and operations more freely without being bound by rigid regulatory frameworks. This flexibility can lead to better responsiveness to customer preferences and market dynamics.
Consumer Benefits: Deregulation is often associated with improved consumer benefits. With increased competition, transportation providers may strive to offer better quality services, enhanced customer experiences, and more competitive pricing. Consumers can enjoy greater options, improved service levels, and potentially lower costs for their transportation needs.

Answer: Short-term memory could be more complex than the information processing model describes and The information processing model is too simple to describe how the brain actually makes memories.
The Information Processing Model is a model of memory that was developed in the 1960s. The model describes the way information flows through different systems of memory during the process of encoding, storage, and retrieval of memories. In this context, which statements are true about the information processing model?There are three components of the Information Processing Model: sensory memory, short-term memory, and long-term memory. According to the model, information from the environment is received and processed by the sensory memory. Sensory memory is then transferred to short-term memory, where it is processed further. Information that is deemed important is transferred to long-term memory where it is stored until it is needed. Hence, the following statements are true about the information processing model:Short-term memory could be more complex than the information processing model describes.The information processing model is too simple to describe how the brain actually makes memories.The above statements are true. The information processing model is considered to be an oversimplified model because the process of memory formation is much more complex than this model describes. The model has been criticized for ignoring the role of emotions, motivation, and other cognitive processes that influence memory formation and retrieval. Nevertheless, the Information Processing Model is still a useful framework for understanding the way we process information in our daily lives.Answer: Short-term memory could be more complex than the information processing model describes and The information processing model is too simple to describe how the brain actually makes memories.
