Among the four countries, Japan, Sri Lanka, and Singapore are all island nations, meaning they are entirely surrounded by water. India, however, is a peninsula and is not an island nation. Therefore, India is different from the rest based on this classification.

Thus, the word that is different from the rest is India.

To solve the analogy problem where the pattern needs to be identified, let’s break it down step-by-step:

The analogy given is: 16 : 56 :: 32 : ?

We need to find the relationship between the numbers 16 and 56 and then apply that relationship to 32 to find the missing number.

1. Find the relationship between 16 and 56:

   • Step 1: Check the operations or patterns. Consider possible operations like addition, subtraction, multiplication, or division.

   • Step 2: Test if multiplication could be a pattern:

     16×3.5=56

     This works as:

     16×3.5=56

     Thus, multiplying by 3.5 seems to be the pattern.

2. Apply the same pattern to 32:

   32×3.5=112

   Therefore, according to this pattern, the number that replaces the question mark should be 112.

3. Verify the other options:

   • 96: This is much larger than expected.
   • 112: Also too large.
   • 121: Similarly, too large.
   • 128: While close, it’s not the result from our multiplication pattern.

Hence, the correct answer is:

112

As teaching is done by 'Teachers' in the 'College' similarly treatment is done by 'Doctors' in the 'Hospital'.

• A : B : C = 150 : 75 : 100 = 6 : 3 : 4

Learning Disability is an umbrella term that encompasses a variety of specific kinds of learning problems. It is a neurological disorder that affects the way one receives and processes information.
Dyspraxia:

• It is a developmental disorder of the brain in childhood causing difficulty in muscle control as well as activities requiring coordination and movement.
• It is a type of learning disability associated with motor skill development, especially fine motor skills. It is also known as Clumsy Child Syndrome or Motor Learning Disability.
• Children with dyspraxia tend to struggle with balance and posture.
• Most individuals with dyspraxia manifest a combination of both ideational or planning dyspraxia and ideomotor or executive dyspraxia wherein ideational or planning dyspraxia affects the planning and coordination, and ideomotor or executive dyspraxia affects the fluency and speed of motor activities.

Hence, it is clear from the points mentioned above that it is dyspraxia that causes problems with movement and coordination.

In the triarchic theory, three types of intelligence proposed by Robert Sternberg are: Analytical, Creative and Practical.

The parameters which must be considered while choosing the teaching methodologies include:
Capacity of the students: Choosing lecture method to teach 6th grade student will not help the teacher to attain his goal of teaching because the child cannot understand the concept just by mere lecturing. Hence to such grade, demonstration method of teaching must be chosen.
Content: Based upon the content, the teacher should decide the methodology.
Nature of the subject: Before deciding the method of teaching, the instructor must keep in mind the nature of the subject because the methods of teaching of science-based subjects is different from those of humanities.

Every child has an interest in listening to stories. So, if a teacher tells interesting stories to students while teaching the subject, it develops an interest in students and they concentrate properly in class.

A school-based assessment is done within the school by the teachers. It makes the learning relevant and can motivate students through the diagnosis of learning gaps. It helps to know the children's strengths and weaknesses. So, the school-based assessment helps all students learn more through diagnosis.
Hence, the correct answer is, 'Helps all students learn more through diagnosis.'

Lawrence Kohlberg, an American psychologist, has propounded the 'Theory of Moral Development'.

• He has made a systematic study of moral development in his theory that is categorized into 3 levels and 6 stages. 

A lesson can be introduced in the class by using examples related to the lesson so that it is easily understandable by children. Telling stories easily attracts students and students find it easy to understand such lessons by story-telling the children like to listen to the stories. That's why teachers introduce lessons with stories.
Hence, the correct answer is "All of these".

Spatial intelligence gives the ability to control and form various mental images. It is related to the multiple intelligence theory.

In a concave mirror when the object is located beyond C the magnification is less than one as the image formed is smaller than the object.

The image of the object can be located on the screen for two positions of convex lens such that u and v are exchanged.
The separation between two positions of the lens is d = 20cm

 

From the figure.
u₁ + v₁ = 90 cm
v₁ − u₁ = 20 cm
Solving
v₁ = 55cm, u₁ = 35cm
From lens formula,

The ratio of angular dispersion to the angle of deviation for the mean wavelength is called Dispersive Power. Represented by 

where δ_v − δ_r is the angular dispersion for violet and red lights and δ_r the deviation suffered by the mean light.

Ultrasound waves are a type of a sound wave which is longitudinal in nature while others are electromagnetic waves because they are transverse in nature.
