Question : In which one of the following is the swim bladder absent?
Option 1: Cuttlefish
Option 2: Bony fish
Option 3: Cartilaginous fish
Option 4: Silverfish
Correct Answer: Cartilaginous fish
Solution : The correct answer is Cartilaginous fish.
A swim bladder, also known as an air bladder, is a gas-filled organ that aids in the control of buoyancy in fish. It is located in the fish's dorsal cavity and is filled with gas produced by the swim bladder gland. Cartilaginous fish lack swim bladders because they do not require them to regulate their buoyancy.
Question : Comprehension: Read the given passage and answer the questions that follow. The Black Drongo also known as the King Crow, is a small Asian bird of the drongo family. Previously, it was seen as a subspecies of the African Fork-tailed Drongo but is now recognised as a full species. It is a common resident breeder in much of tropical southern Asia from southwest Iran through India and Sri Lanka to southern China and Indonesia. It is a wholly black bird with a distinctive forked tail and measures 28 cm in length. Feeding on insects, it is commonly found in open agricultural areas and light forest areas throughout its range, perching conspicuously on a bare perch or along power or telephone lines. The species is famous for its aggressive behaviour towards much larger birds, such as crows, and never hesitates to dive-bomb any birds of prey that invade its territory. Smaller birds often nest in the well-guarded vicinity of a nesting Black Drongo. The Black Drongo has been introduced to some Pacific islands, where it has thrived and become abundant to the point of threatening and causing the extinction of native and endemic bird species there. Drongos fly with strong flaps of the wing and are capable of fast manoeuvres that enable them to capture flying insects. With short legs, they sit upright on thorny bushes, bare perches or electricity wires. They may also perch on grazing animals. The Black Drongo is found predominantly in open country and usually perches and hunts close to the ground. They are mostly aerial predators of insects but also glean from the ground or off vegetation. They are found as summer visitors to northeastern Afghanistan and northern Pakistan but are mainly resident south from the Indus Valley up to Bangladesh and into India and Sri Lanka. Question: What was the impact of trying to introduce the species to the Pacific islands?
Option 1: They decreased in numbers drastically.
Option 2: They returned to the lands of their origin.
Option 3: They proved to be a threat to the local birds.
Option 4: They did not survive in the changed climate conditions.
Correct Answer: They proved to be a threat to the local birds.
Solution : The third option is the correct choice.
The impact of introducing the Black Drongo species to some Pacific islands was that they thrived and became abundant to the point of threatening and causing the extinction of native and endemic bird species there.
The passage states that the Black Drongo has been introduced to these islands, and as a result of its successful establishment and proliferation, it poses a threat to the local bird species.
Question : Directions: Three of the following four-letter clusters are alike in a certain way and one is different. Pick the odd one out.
Option 1: FUGT
Option 2: PKQJ
Option 3: MONM
Option 4: JQKP
Correct Answer: MONM
Solution : Let's check each option – First option: FUGT; F is the opposite letter for U, and G is the opposite letter for T. Second option: PKQJ; P is the opposite letter for K, and Q is the opposite letter for J. Third option: MONM; M is the opposite letter for N, and N is the opposite letter for M. Fourth option: JQKP; J is the opposite letter for Q, and K is the opposite letter for P.
So, the third option is different from the other three options. Hence, the third option is correct.
Question : Professor ______, who won the Nobel Prize in Chemistry in 2019, is the oldest Nobel laureate ever.
Option 1: Joachim Frank
Option 2: John Goodenough
Option 3: George Smith
Option 4: Gregory Winter
Correct Answer: John Goodenough
Solution : The correct answer is John Goodenough.
John Goodenough won the Nobel Prize in Chemistry in 2019, and he was the oldest person to receive a Nobel Prize in the field of chemistry. He received the Nobel Prize at the age of 97 years. He was honoured for his valuable contribution to the development of Lithium-ion batteries.
Question : Directions: What was the day of the week on the 24th of August 1923?
Option 1: Monday
Option 2: Sunday
Option 3: Thursday
Option 4: Friday
Correct Answer: Friday
Solution : Code for months –
Code for days –
Code for centuries –
For, 24th of August 1923 – Formula: {Date + (Month code) + (Century code) + ( last two digit of the year) + ((last two digit of the year / 4)'s Quotient)} / 7
Date = 24 Code for the month (August) = 2 Code for the century (1900) = 0 (1923 = 1900 + 23; For 1900 it will be 0 and for 23 it will be 23) And, 23 ÷ 4 = 5(Quotient) Now, on adding them we get→24 + 2 + 0 + 23 + 5 = 54 On dividing 54 by 7, we get 5 as a remainder. 5 is the code for Friday.
So, the 24th of August 1923 will be Friday. Hence, the fourth option is correct.

Question : Directions: Three of the following four letter–clusters are alike in a certain way and one is different. Pick the odd one out.
Option 1: TNH
Option 2: LFZ
Option 3: PJF
Option 4: DXR
Correct Answer: PJF
Solution : Let's check each option – First option: TNH; T – 6 = N, N – 6 = H Second option: LFZ; L – 6 = F, F – 6 = Z Third option: PJF; P – 6 = J, J – 4 = F Fourth option: DXR; D – 6 = X, X – 6 = R
The third option is different from the other three options because the difference in the position value of the letters is 4 instead of 6. Hence, the third option is correct.
Question : Directions: Select the missing number from the given responses.
Option 1: 10
Option 2: 20
Option 3: 22
Option 4: 110
Correct Answer: 20
Solution : In a column, determine the square root of the first number to get the second number, and then multiply the second number by 2 to get the third number.
In the first column: $\sqrt36$ = 6 and 6 × 2 = 12 In the second column: $\sqrt64$ = 8 and 8 × 2 = 16 Similarly, follow the same pattern in the third column: $\sqrt100$ = 10 and 10 × 2 = 20
So, 20 is the missing number in the given matrix. Hence, the second option is correct.
Question : Directions: Select the option related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term. 11 : 132 :: ? : 342 :: 22 : 506
Option 1: 17
Option 2: 19
Option 3: 18
Option 4: 20
Correct Answer: 18
Solution : Given: 11 : 132 :: ? : 342 :: 22 : 506
Add one to the first number and multiply the resultant by the first number – Like, 11 : 132→11 × (11 + 1) = 132 And, 22 : 506→22 × (22 + 1) = 506 Similarly, follow the same pattern for ? : 342→ ⇒ a × (a + 1) = 342 ⇒ a2 + a – 342 Solving for a, we get, a = 18, a = –19
Therefore, 18 is the required missing number. Hence, the third option is correct.
