ISSB Intelligence Test: Quiz!

Explanation
The given sequence is a list of prime numbers. Starting with 1, the next prime number is 2, but it is not given as an option. The next prime number after 2 is 3, which matches with the given sequence. Therefore, the missing number is 13.

Explanation
The given sequence consists of prime numbers starting from 2. Each subsequent number is obtained by adding 2 to the previous number. Therefore, the missing number in the sequence should be 13 + 2 = 15.

Explanation
The given sequence is a series of perfect squares. Each number is the square of the next natural number. For example, 1 is the square of 1, 4 is the square of 2, 9 is the square of 3, and so on. Therefore, the missing number in the sequence is 36, which is the square of 6.

Explanation
The sequence you provided appears to follow an arithmetic pattern. Each number is obtained by adding a certain value to the previous number. Let's find the pattern:

2 + 1 = 3
3 + 2 = 5
5 + 3 = 8

It seems like the pattern is to add the next positive integer to the previous number. Following this pattern:

5+8 = 13

So, the next number in the sequence is 13.

Explanation
The pattern in the given sequence is that each number is divided by 2 to get the next number. Starting with 124, dividing it by 2 gives 62, then dividing 62 by 2 gives 31, and so on. Therefore, the next number in the sequence would be 15.5.

Explanation
In the given pattern, each letter is followed by the next letter in the alphabet. Additionally, each letter is followed by the letter that comes two positions after it in the alphabet. Following this pattern, the missing letters after G would be I and K. Therefore, the correct answer is I K.

Explanation
The pattern in the given sequence is that each letter in the first set is moved two positions forward in the alphabet to obtain the corresponding letter in the second set. Similarly, each letter in the second set is moved two positions forward in the alphabet to obtain the corresponding letter in the third set. Applying the same pattern, the third set should be moved two positions forward in the alphabet to obtain the letters in the fourth set. Therefore, the correct answer is IKJ.

Explanation
The given question asks to identify the odd item out of Apple, Potato, Mango, and Orange. All the options except Potato are fruits, whereas Potato is a vegetable. Therefore, Potato is the odd one out in this group.

Explanation
In the given sequence, each letter is followed by the next letter in the alphabet, with one letter omitted in between. For example, A is followed by C, omitting B. Following this pattern, the correct choice should have been MO instead of MN.

Explanation
The word "Player" is the odd one out because it does not belong to the medical field like the other options. "Doctor," "Patient," and "Medicine" are all related to the healthcare industry, while "Player" is unrelated to medicine or healthcare.

Explanation
The numbers 24, 36, and 64 are all even numbers because they are divisible by 2. However, 45 is an odd number because it is not divisible by 2.

Explanation
The word "fever" is the correct answer because it is the only option that is a noun and relates to a medical condition. "Less," "few," and "little" are all adjectives and do not fit the context of the question.

Explanation
The relationship between a son and a father is that of a child and parent. Similarly, the relationship between a nephew and an uncle is that of a child and a sibling of one's parent. Therefore, the correct answer is Uncle.

Explanation
The analogy presented in the question is a comparison between the degrees of quality. "Good" is a positive adjective, and "better" represents a higher degree of goodness. Similarly, "bad" is a negative adjective, and the correct answer "worse" represents a higher degree of badness.

Explanation
Given that A is shorter than B and taller than both C and D, it follows that B is taller than A, C, and D.

Explanation
The given list consists of cities, but Lahore is different because it is the only city that is not a capital. Beijing is the capital of China, Dhaka is the capital of Bangladesh, and Kabul is the capital of Afghanistan. Lahore, on the other hand, is a major city in Pakistan but not its capital (Islamabad is the capital of Pakistan).

Explanation
The given sequence follows a pattern where each number is formed by taking the digit in the units place of the previous number, followed by the digit in the tens place, and finally the digit in the hundreds place. Therefore, the next number in the sequence would be formed by taking the digit 2 from 234, followed by the digit 3 from 342, and finally the digit 4 from 423, resulting in the number 234.

Explanation
The word "Adult" is the only option in the list that does not refer to a stage of early development or infancy. "Child," "Baby," and "New born" all represent different stages of growth and development in human life, whereas "Adult" refers to a fully developed and mature individual.

Explanation
A railway station always has a railway line because it is the essential infrastructure that allows trains to arrive and depart from the station. Without a railway line, there would be no means for the trains to reach the station, making it impossible for passengers to board or alight from the trains. The railway line connects the station to other stations and forms the backbone of the transportation network.

Explanation
The analogy "Men is to Women as Boy is to Girl" is based on the relationship between genders. Men and women are adult counterparts, and similarly, boys and girls are child counterparts. Therefore, the correct answer is "Girl" as it is the counterpart of a boy, just as a woman is the counterpart of a man.

Explanation
The given question states that if South-East becomes North, North-East becomes West, and so on. Following this pattern, if West becomes South, the correct answer would be "South East".

Explanation
To determine the direction the man is from his starting point, let's break down each segment of his journey:
He starts by walking 5 km south.
He then turns to his right. Since he was originally heading south, turning right would direct him west. He walks 3 km west.
After that, he turns left. From west, turning left would mean he is now heading south again. He walks another 5 km south.
So, he has moved:
5 km south + 5 km south = 10 km south
3 km west
To find the direction from the starting point to where he is now, visualize this as a right triangle where the legs are 10 km (south) and 3 km (west). The direction from the starting point is along the hypotenuse of this triangle, pointing from the origin (starting point) toward the point labeled (3, 10) on a coordinate plane where west and south are the negative axes.

Explanation
When the minute hand of a clock points towards the west (270 degrees), the hour hand will point towards the east (90 degrees).
Therefore, the correct answer is East.

Explanation
The man initially walks 30m towards the North. Then, he takes a left turn and walks 40m. After that, he takes another left turn and walks 30m. Since he took two left turns, he essentially made a complete 180-degree turn and is now facing South. The distance from the starting point is the same as the distance he walked towards the South, which is 30m. Therefore, he is 30m away from the starting point.

Explanation
Starting Point: He begins at a given starting position.
First Leg: He walks 20 meters towards the South.
Second Leg: Then he turns to his right and walks 30 meters. Since he was originally moving South, turning to his right would point him West.
Third Leg: Then he turns to his left and walks 20 meters. After moving West, a left turn would make him face South again.
Fourth Leg: Finally, he turns to his left and walks 30 meters. Since he was facing South, turning left would direct him East.
At the end of these movements:
He has moved 20 meters South and then 20 meters South again, totaling 40 meters South.
He has moved 30 meters West and then 30 meters East, which cancels out these movements in the East-West direction.
Thus, his net movement is 40 meters directly South from his starting position. Since there's no displacement in the East-West direction, and he only moved South, he is 40 meters away from his starting position.
