The correct answer is "ถูกทุกข้อ" which means "all of the above." This suggests that the principle for making decisions in choosing technology is to consider all of the factors mentioned in the options: usefulness, cost-effectiveness, and safety. In other words, when making decisions about technology, it is important to consider its benefits, cost-efficiency, and safety measures.

The question asks which subject is not related to design and technology. The correct answer is "พยาบาลศาสตร์" (Nursing). This subject is not typically associated with design and technology, as it focuses more on healthcare and patient care rather than the design and development of technological systems or products.

The correct answer is ง. ถูกทุกข้อ (All of the above). This is because the 7 steps of the technology process include defining the problem or requirements, gathering data, selecting methods, designing and implementing, testing, improving and correcting, and evaluating the results. All of these steps are necessary in the technology process to ensure successful outcomes.

The correct answer is "ข. ปรับปรุงและแก้ไข" (b. Improve and fix). This answer suggests that if a flaw or defect is found in the work, the next step should be to make improvements and corrections to address the issue. This could involve identifying the problem, analyzing its cause, and implementing changes to rectify it. This process helps to ensure that the work meets the required standards and quality.

Closed-circuit television (CCTV) cameras are a beneficial technology for enhancing security. They can be used to monitor and record activities in various settings, such as homes, businesses, and public spaces. CCTV cameras can help deter crime, provide evidence in investigations, and allow for real-time monitoring of suspicious activities. By capturing footage of potential security threats, CCTV cameras contribute to maintaining a safe environment and preventing criminal activities.

Technology refers to all of the above options. It encompasses the things that humans create and develop, the application of scientific knowledge to create useful products and processes, and the creation of tools and systems to meet basic needs and improve efficiency in work and problem-solving.

Technology is important for various reasons. It helps humans survive by providing essential needs such as food, clothing, and medicine. It also improves the standard of living, making life more convenient and comfortable. Additionally, technology helps solve problems caused by natural disasters, as humans need to find ways to prevent and mitigate these issues. Therefore, all the given options are correct in highlighting the importance of technology.

The question is asking for the item that is produced using knowledge of physics related to force and motion. It states that when the handle is pressed down in a lever-like motion, the floating ball moves upward, causing the water release system to work. The correct answer is "ถังน้ำซักโครก" (washing machine) because it is a household appliance that operates using a lever mechanism and the force and motion principles described in the question.

The correct answer is เตาไมโคเวฟ (microwave). This is because a microwave uses microwave energy to generate vibrations in the water molecules present in the food, causing them to heat up and cook the food.

The correct answer is ง. ถูกทุกข้อ (All of the above). This is because in order for technology to be able to solve problems or meet human needs, it requires the collaboration of all five components mentioned in the options. The input represents the human needs or problems, the technological process is the steps taken to solve the problems, the output is the result or product of the technology, and the factors that can support or hinder technology include beliefs, attitudes, religion, culture, and traditions. Therefore, all of these components are necessary for technology to effectively address human needs and solve problems.

The question asks about the design of children's toys and mobile phones, and which subject is related to the design. The answer is "ศิลปศาสตร์" (Art) because art is related to designing beautiful and aesthetically pleasing objects, which is important in designing toys and mobile phones.

Technology processes are important because they help to solve problems and meet needs. Technology allows us to find solutions to various challenges and fulfill our desires. It enables us to create innovative solutions and improve our quality of life. By utilizing technology, we can address issues and meet the demands of individuals and society as a whole.

The correct answer is "ค. การออกแบบและปฏิบัติการ" which translates to "c. Design and execution" in English. This answer is correct because in the process of creating a 3D image, the design and execution phase is where the actual creation of the artwork takes place. This involves planning and designing the image, as well as executing the design using various techniques and tools. The other options, such as improving and correcting, problem definition, and data collection, are not directly related to the process of creating a 3D image.

The correct answer is "ก. ด้านความเหมาะสมกับสภาพท้องถิ่น" which means "Suitability for local conditions" in English. This answer suggests that the artificial rain-making technology is beneficial because it can be adjusted and adapted to meet the specific needs and conditions of a particular region or area. It implies that this technology can be customized to address the unique challenges and requirements of different local environments, making it a useful and advantageous solution.

The given question asks about the field of study that involves analyzing human needs, communicating with others using listening, speaking, reading, and writing skills, exchanging ideas with others, and solving problems together. The field that best relates to these activities is "มนุษยศาสตร์" or Humanities. Humanities is a field of study that focuses on human culture, behavior, and society, which includes language, communication, and problem-solving skills. Therefore, the correct answer is ค. มนุษยศาสตร์ (Humanities).

The question asks for the option that is not a technological resource. Option ก includes agricultural products such as crops, vegetables, and fruits, as well as livestock. These are not considered technological resources as they are natural resources that are cultivated or raised by farmers. Technological resources refer to human-made tools, machinery, equipment, data, information, materials, energy, capital, and assets.

The reason why the process of technology requires a method selection is because it aims to obtain the best problem-solving method. This implies that there are multiple methods available, and the selection process is necessary to determine which method will be the most effective and efficient in solving the problem at hand.

The correct answer is ง. สังคมศาสตร์ (Social Sciences). This is because the survey on resource usage and the development of a recycling bank project involves studying the behavior and interactions of individuals and communities in relation to the use of paper, glass, and plastic resources. Social sciences, such as sociology and anthropology, focus on understanding human behavior and social interactions, making it relevant to analyze the data from the survey and develop the recycling project.

The correct answer states that a grinder is a better option compared to a mortar and pestle because it saves time, labor, and is cheaper. This is because a grinder can quickly and efficiently grind ingredients, reducing the time and effort required compared to manually grinding with a mortar and pestle. Additionally, grinders are often more affordable and accessible compared to traditional tools like mortar and pestle.

The correct answer is "ก. การประเมินผล" which means "Evaluation" in English. In the process of technology, evaluation plays a crucial role in determining the success and effectiveness of the implemented solution. It helps to assess whether the desired outcomes and goals have been achieved or not. Evaluation allows for feedback and improvements to be made, ensuring that the technology meets the required standards and satisfies the needs and expectations of the users.
