In a certain country, the supply of dairy products consistently exceeds the demand. To support farmers, the government purchases all excess dairy products. Recently, a study recommended that people should consume fewer high-fat dairy products for better health. As a result, the demand for skim milk has increased, while the demand for butter, which is high in fat, has decreased.
Which of the following can be inferred from the information given above?
(A) The government will purchase more butter than before to support farmers.
(B) The overall demand for dairy products will decrease due to health concerns.
(C) Farmers will start producing more skim milk to meet the changing demand.
(D) The price of butter will increase as a result of decreased demand.
(E) The government's support for farmers will lead to an oversupply of skim milk.

With advancements in technology, most industries have seen an increase in production efficiency, leading to reduced costs for products and services. However, in the field of higher education, tuition fees have been growing at a rate far exceeding inflation. Some experts explain that increased efficiency in the education industry would lead to lower wages for teachers, thus affecting the quality of education. To maintain the quality of education, schools have no choice but to raise tuition fees to sustain teachers' salary levels.
Which of the following, if true, would most weaken the experts' explanation above?
(A) Despite the continuous rise in tuition fees, the salary growth rate of most university teachers remains lower than the inflation rate.
(B) A survey of university teachers shows that the vast majority believe their teaching efficiency and quality have not improved due to the increase in tuition fees.
(C) Compared to tuition fees, other costs of higher education, such as textbook fees and accommodation fees, are growing at a faster rate.
(D) Most economists believe that even in a deflationary environment, tuition fees for higher education will not decrease.
(E) To cope with rising tuition fees, more and more students are choosing to complete their first two years of courses at community colleges before transferring to four-year universities.

AA


2.RC
Scarcity appeals in advertising enhance value perception, which in turn impacts purchase intentions. This study suggests that the impact of perceived value on purchase intention is mediated by consumers' perceptions of personal susceptibility and the susceptibility of others. Results of an experimental study support a mediating effect where enhanced value perception leads to increases in perceived influence on self relative to others, and therefore enhances purchase intention. The results confirm the impact of perceptual biases as suggested by the "third-person effect," thus providing some interesting theoretical contributions for advertising research as well as for managerial implications.

Products that have limited availability can induce consumers to evaluate those products more favorably. As valuable products (such as tickets for concerts of famous artists) are often scarce, consumers infer that those products are valuable (Jung and Kellaris 2004). Scarcity effects on value perception have revealed broad empirical support (Lynn 1991). Marketers make frequent use of this effect and base promotional claims on the principle of scarcity, using phrases like "limit one per customer," "limited release," "only while supplies last," or "limited time only." Over the past few years, it has also become a popular practice in home-shopping television to count down the number of products to indicate that "supplies are dwindling fast." In this study, it is assumed that scarcity appeals in mass media advertising lead to a direct effect on perceived value and purchase intention, as well as an additional effect that is based on perceptions of susceptibility. Those perceptions result from the so-called third-person effect. The perceptions mediate the impact of value perception for scarcity appeals and can contribute to increased purchase intention. This study suggests that people take into consideration the perceived influence on self and the perceived influence on others; the impact of value perception increases with higher perceived influence on self relative to others.

The question arises as to what happens when items that are less desirable (due to wide availability) are advertised. Value perceptions should be lower and lead to perception of lower personal susceptibility, but to increased susceptibility of others. This, in turn, can strengthen the belief that the offer does not provide a unique value, which means that purchase intentions may decrease. There may be moderating variables that can lead to other conclusions, however. One main issue may be the cause for scarcity. Although this study was investigating the case of scarcity dependent on limited supply, scarcity can also result from high demand. In such a case, the perceived value may be lower since it would not contribute to satisfying one's need for uniqueness. This result may also depend on cultural differences, however, as the need for uniqueness can differ for individualistic and collectivistic cultures. While individualistic cultures may have a high need for uniqueness, scarcity may serve as a means to distinguish oneself from others and foster higher perceived value in cases where scarcity is based on limited supply. For collectivists, however, the perceived value may increase when scarcity is based on high demand, as it indicates high popularity, and the possession of such items would contribute to the feeling of being part of a group. In turn, the perceived influence on others may also have different impacts. High perceived influence on others relative to self for items that are scarce because of high demand would strengthen the need to be part of a group, but it would weaken the possible contribution to uniqueness. On the other hand, if items are scarce because of limited supply, they enhance uniqueness, particularly for individualistic cultures. Future research should focus on such variables that mediate or moderate the described scarcity effects that possibly play a role for the investigated perceptions of susceptibility. Besides the cause of scarcity and the impact of culture on need for uniqueness, further variables can be considered as moderators or mediators, such as individual variables (e.g., self-esteem or the confidence in one's ability to resist influence attempts, age, and education of recipients) or the way hypothetical others are defined in terms of social distance.

The inexorable march of artificial intelligence (AI) and robotics has permeated myriad industries, and the gastronomic realm is no exception. The advent of AI-powered culinary technology portends a seismic shift in the way we prepare, consume, and manage our sustenance. A recent study conducted by the International Food Information Council (IFIC) revealed that a staggering 62% of consumers evince a keen interest in harnessing the power of AI-assisted kitchen appliances to facilitate healthier dietary choices.

One of the most propitious applications of AI in the culinary domain is the development of smart refrigerators. These sophisticated appliances employ an amalgamation of computer vision and machine learning algorithms to identify and monitor the contents of the refrigerator, proffering recipe suggestions based on the available ingredients and alerting users when items are nearing their expiration date. A 2020 report by Mordor Intelligence prognosticated that the global smart refrigerator market will burgeon to $8.1 billion by 2025, exhibiting a compound annual growth rate (CAGR) of 13.2% during the forecast period.

Another area where AI is making significant strides is in the realm of personalized nutrition. By analyzing an individual's genetic data, health markers, and dietary predilections, AI algorithms can generate bespoke meal plans and recipes tailored to their idiosyncratic needs. This approach has the potential to revolutionize the way we approach nutrition, particularly for those with specific health conditions or dietary restrictions. A 2021 study published in the Journal of the American Medical Informatics Association found that AI-generated personalized nutrition plans led to a 22% improvement in adherence to dietary recommendations compared to traditional one-size-fits-all approaches.

However, the integration of AI in the culinary sphere is not without its challenges. One of the primary concerns is the issue of data privacy and security. As AI-powered kitchen appliances collect copious amounts of personal data, including eating habits and health information, there is a risk of this data being compromised or misused. A 2019 survey by the Pew Research Center revealed that an astonishing 79% of Americans harbor concerns about the way companies utilize their personal data, underscoring the need for robust data protection measures in the development and deployment of AI kitchen technology.

Another challenge is the potential impact of AI on the culinary workforce. As AI-powered robots become increasingly sophisticated, there is a risk of job displacement in the food service industry. A 2018 report by the McKinsey Global Institute estimated that up to 73% of activities in the food service industry have the potential for automation, raising concerns about the future of human workers in the culinary field.

Despite these challenges, the potential benefits of AI in the kitchen are manifold. By leveraging the power of AI and robotics, we can create a more efficient, sustainable, and health-oriented culinary ecosystem. As the technology continues to evolve, it will be imperative to address the ethical and social implications of AI in the kitchen to ensure that its benefits are realized while minimizing potential risks. A 2020 study by the Institute for the Future (IFTF) posited that the judicious application of AI in the culinary industry could lead to a 35% reduction in food waste, a 28% decrease in energy consumption, and a 17% increase in the nutritional value of meals by 2030.

Moreover, the convergence of AI, the Internet of Things (IoT), and big data analytics is expected to give rise to a new paradigm of "smart kitchens" that can anticipate and cater to the specific needs and preferences of individual users. A 2021 report by Gartner predicted that by 2025, 47% of households in developed countries will have at least one smart kitchen appliance, up from just 12% in 2020. This rapid adoption of AI-powered culinary technology is expected to create a market opportunity worth $43.5 billion by 2027, according to a 2021 report by Grand View Research.

However, the widespread adoption of AI in the kitchen also raises pertinent questions about the role of human creativity and expertise in the culinary arts. While AI can optimize recipes and streamline cooking processes, it remains to be seen whether it can truly replicate the intuition, passion, and artistry that human chefs bring to the table. A 2019 survey by the Culinary Institute of America found that 92% of professional chefs believe that human creativity and expertise will remain essential in the culinary industry, even as AI becomes more prevalent.

In conclusion, the integration of AI in the kitchen represents a transformative development that promises to reshape the way we interact with food. By harnessing the power of machine learning, computer vision, and big data analytics, AI-powered culinary technology has the potential to revolutionize the way we cook, eat, and manage our dietary habits. However, as with any disruptive technology, the adoption of AI in the kitchen also presents significant challenges and ethical considerations that must be addressed to ensure its responsible and equitable deployment. As we navigate this uncharted territory, it will be crucial to strike a balance between the benefits of AI and the preservation of human creativity, expertise, and social values in the culinary realm.
