On decoding L θ Z β T means L is the mother of Z and Z is the sister of T.

i) L is mother of T → True
ii) L is father of T → False (as L is mother of T) 
iii) T is father of L → False (as T is either son or daughter of L)
iv) Z is daughter of T → False (as Z is sister of T)
Hence, 'L is mother of T' is the correct answer.

Explanation:
The round robin CPU scheduling algorithm is a time-sharing system where each process is executed for a fixed time slice called a time quantum. Once the time quantum expires, the CPU is preempted and the next process in the queue is executed. This process continues until all processes have been executed.
Now, let's analyze the statements given in the question:
A: Using very large time slice degenerates into first come first serve algorithm
- When a large time slice is used, each process is allowed to run for a longer duration before being preempted.
- This essentially means that the CPU is allocated to each process in a sequential manner, following the order in which they arrived.
- Therefore, using a large time slice in round robin scheduling effectively degenerates into the first come first serve algorithm.
B: Using extremely small time slices improves performance
- Using extremely small time slices can lead to a high overhead due to the frequent context switches between processes.
- Context switching involves saving the current state of a process and loading the state of the next process, which incurs additional time.
- This overhead can degrade the overall system performance, especially when the number of processes is large.
C: Using extremely small time slices degenerates into last in first out algorithm
- This statement is not accurate. Using extremely small time slices does not lead to a last in first out algorithm.
- In round robin scheduling, the order of execution is based on the arrival time of the processes, not the order in which they were added to the queue.
D: Using medium-sized time slices leads to shortest request time first algorithm
- This statement is also not accurate. The round robin scheduling algorithm does not prioritize processes based on their request time.
- Instead, it ensures that each process gets an equal share of the CPU's time by using a fixed time slice.
Therefore, the correct answer is:
A: Using very large time slice degenerates into first come first serve algorithm

ARP (Address Resolution Protocol) is:
- A TCP/IP protocol used to dynamically bind a high level IP address to a low-level physical hardware address:
- ARP is a protocol used in TCP/IP networks to map an IP address to a corresponding physical MAC address.
- It allows devices on a local network to communicate with each other using their hardware addresses.
- ARP resolves IP addresses to MAC addresses on the same network segment.
- A TCP/IP high-level protocol for transferring files from one machine to another:
- This statement is incorrect. ARP is not used for file transfer; it is specifically used for address resolution.
- A protocol used to monitor computers:
- This statement is incorrect. ARP is not used for monitoring computers. It is solely used for address resolution.
- A protocol that handles error and control messages:
- This statement is incorrect. ARP is not responsible for handling error and control messages. It is solely used for address resolution.
Conclusion:
The correct answer is A: A TCP/IP protocol used to dynamically bind a high-level IP address to a low-level physical hardware address. ARP is essential for communication within a local network, allowing devices to find each other using their IP and MAC addresses.

To determine the number of bytes represented by a KB (kilobyte), we need to understand the conversion factor between kilobytes and bytes.
- 1 kilobyte (KB) = 1,024 bytes
Given the options provided, we can determine that the correct answer is option B, which states that a KB represents 1,000 bytes.
Here is a breakdown of the options and their representations in bytes:
- Option A: 8 bytes - This is not the correct answer as 8 bytes is much smaller than a kilobyte.
- Option B: 1,024 bytes - This is the correct answer as 1 kilobyte is equal to 1,024 bytes.
- Option C: 1,000,000 bytes - This is not the correct answer as 1 kilobyte is much smaller than 1,000,000 bytes.
- Option D: 1,000,000,000 bytes - This is not the correct answer as 1 kilobyte is much smaller than 1,000,000,000 bytes.
Therefore, the correct answer is option B, which states that a kilobyte represents 1,024 bytes.

Cooperation teaches the values of committing oneself to the common good, seeing success as depending on the efforts of all participants, feeling happy when others succeed, seeing others as resources to help one succeed, viewing worth as unconditional, and viewing diverse others in positive ways.
Cooperative learning is a teaching way for students to learn essential interpersonal life-skills and develop the ability to work collaboratively, a skill now greatly in demand in the workplace. Thus, it provides faster and efficient learning. In cooperative learning, the diverse students in the school are to be transformed into a symphony. Students need positive self-esteem, the psychological health to face conflict and challenge, and the social competencies required to work effectively with diverse peers. Personal and superordinate identities are developed through group processes.

The instructions of a teacher must be based on the child's abilities, aptitude and interest. His ability to grasp and apply things, his natural ability to justify learning and his interest to learn a particular thing could decide the teaching strategies, as the education these days has become more child-centered. The teacher must be aware of the child's abilities, aptitude, and interest, which is possible only through proper evaluation.

The teacher must exhibit a friendly behaviour with the students. A warm and cordial relationship with the students is always welcomed. The teacher can then understand the mentality and accordingly take necessary steps to eliminate undesired behaviour of the students.

Mathematics is a science that involves dealing with numbers, different kinds of calculations, measurement of shapes and structures, organization and interpretation of data, establishing relationships among variables, etc.

• During the sixth century B.C. Pythagoreans (Pythagoras and his followers) coined the term Mathematics.
• Mathematics is derived from the Greek word ‘Ganita’ which means ‘inclined to learn.

Key Points For effective mathematics teaching:

• Mathematics education should be made more relevant to students by tying it to their real-life studies.
• Every mathematical thought should be pondered through diverse activities so that the child can obtain a better conceptual understanding and the learning-teaching process can become more pleasurable.
• Using several strategies and approaches to obtain a solution or solve a problem; using a typical or standard method to tackle an issue can lead to rote learning and should be avoided if feasible.
• To make teaching more effective, a teacher should connect concepts to their prior knowledge and real-life experiences, and strive to pique their interest and curiosity.
• Learning experiences and material in mathematics should be selected with due consideration to situations that will
  • it pupils for useful service to the community,
  • discover vocational possibilities,
  • develop the ability to analyze and solve the problems of life.

Thus, it can be inferred that using standard methods to solve problems is not good for mathematics teaching.

Additional Information Every child learns through his /her own experience and then sometimes device his/her strategies for learning.

• Children come across situations in their everyday affairs where they use some mathematical knowledge.
• Teachers need to consider the ability of their students, and as far as possible various activities should be organized in the classroom to enhance the creative abilities of students.
• The teacher, who connects mathematical concepts with the objects around the students, can be considered a successful teacher.
• Cognitive structures are constructed and continuously reconstructed through interaction between the student and various experiences in and out of the classroom.

A pyramid is a polyhedron that has a base, which can be any polygon, and three or more triangular faces that meet at a point called the apex. These triangular sides are sometimes called the lateral faces to distinguish them from the base.

In ΔABC, we have

θ = 30°, AB = 200 m

Then, sin 30° = Perpendicular / Hypotenuse

= AB / AC

⇒ 1 / 2 = 200 / AC

⇒ AC = 400 m.

Mathematics is the study of geometrical figures, their co-relation, and their dependency on each other. It deals with quantity, measurement, and spatial relationships. It relies on logic, reasoning, problem-solving, creativity, and mathematical way of thinking.

Key Points

• The most appropriate strategy for teaching students to solve mathematical problems at the upper primary level is to provide the learners with experiential learning in context as:
  • Experiential learning is self-initiated as the learner willingly takes the initiative to engage in such type of learning.
  • The learner himself evaluates the results and outcomes of such learning by applying it to the realization of learning objectives.
  • It leaves a pervasive effect on the learner. Whatever is learned through this method can be made into use when and where he needs it.

Hint

• It is important that conceptual understanding should not made on rote-memorization but should based on real and concrete experiences.
• The open-ended questions should be asked as these types of questions provide insight to the learner's mind and help teacher to see the things from a student's perspective.
• The problem-solving approach should be encouraged as it can stimulate purposeful reflective thinking in arriving at a solution. The children took the problem as a challenge that enables them to have mastery over a specific concept.

Hence it is concluded that the most appropriate strategy for teaching students to solve mathematical problems at the upper primary level is to provide the students with experiential learning in context.

Answer: B. Leader

Explanation:
The analogy can be understood as follows:

- A doctor is a professional who provides medical care and is usually in a higher position than a nurse. A nurse is a healthcare professional who assists and supports the doctor in providing medical care. Thus, a nurse follows the instructions given by the doctor.

- Similarly, a leader is a person who provides guidance, direction, and support to a group of people or an organization. A follower is a person who supports and follows the instructions, ideas, or policies of the leader.

Hence, the correct option to complete the analogy is:

Doctor : Nurse :: Leader : Follower
