Scientists have further (4) ________ the tiger into nine subspecies: the extinct Bali, Caspian, and Javan subspecies, and the living Malayan, Sumatran, South China, Indochinese, Bengal, and Amur (or Siberian) subspecies. Of these six subspecies, AZA-accredited zoos currently manage three: Amur, Malayan, and Sumatran. The Smithsonian's National Zoo and Conservation Biology Institute is home to Sumatran and Amur tigers; Sumatran tigers are (5) ________ as critically endangered on the International Union for Conservation of Nature's Red List, and Amur tigers have been classified as endangered. Question: Select the most appropriate option to fill in the blank number 1.
Option 1: long
Option 2: small
Option 3: blunt
Option 4: sharp
Correct Answer: sharp
Solution : The fourth option is the correct choice.
The context describes tigers as powerful hunters with certain characteristics. In this context, the word sharp is a fitting choice for the blank, as it complements the idea of powerful hunters, referring to sharp teeth. This adjective adds to the description of the tiger's physical attributes, emphasising the sharpness of their teeth.
Therefore, the correct answer is sharp.
Question : The discovery and understanding of electromagnetic induction is based on a long series of experiments carried out by ______.
Option 1: Planck and Fermi
Option 2: Einstein
Option 3: Faraday and Henry
Option 4: Rutherford
Correct Answer: Faraday and Henry
Solution : The correct answer is Faraday and Henry.
The exploration and comprehension of electromagnetic induction resulted from extensive experiments conducted by Michael Faraday and Joseph Henry. Through their observations, Faraday deduced that an electromotive force (emf) is generated when there is a dynamic change in magnetic flux across a coil over time. This groundbreaking insight laid the foundation for the principles of electromagnetic induction, influencing the development of various electrical devices and technologies.
Question : The adoption of the High Yielding Variety Programme in Indian Agriculture started in.
Option 1: 1968
Option 2: 1967
Option 3: 1966
Option 4: 1965
Correct Answer: 1966
Solution : The correct answer is 1966.
The High Yielding Variety Programme (HYVP) was established in 1966 to achieve food self-sufficiency by 1970-71. The program's fundamental idea was to boost food grain productivity using the most recent crop input varieties. This program in the fourth five-year plan was a breakthrough in India's agricultural development history.
Question : Directions: If + means −, − means ×, × means ÷ and ÷ means +, what will come in place of (?) in the following equation? 79 ÷ 64 × 8 − 7 + 12 = ?
Option 1: 123
Option 2: 117
Option 3: 138
Option 4: 147
Correct Answer: 123
Solution : Given: + means −, − means ×, × means ÷ and ÷ means + 79 ÷ 64 × 8 − 7 + 12 = ?
After interchanging the given mathematical signs, we get – ⇒ 79 + 64 ÷ 8 × 7 – 12 ⇒ 79 + 8 × 7 – 12 ⇒ 79 + 56 – 12 = 123
So, 123 is the answer to the given equation. Hence, the first option is correct.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13-Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (7, 35, 42); (4, 20, 24)
Option 1: (8, 56, 72)
Option 2: (6, 36, 48)
Option 3: (9, 45, 54)
Option 4: (12, 60, 48)
Correct Answer: (9, 45, 54)
Solution : Given: (7, 35, 42); (4, 20, 24)
Like, (7, 35, 42)→7 × 5 = 35; 7 × 6 = 42 (4, 20, 24)→(4 × 5) = 20; 4 × 6 = 24
Let's check the options – First option: (8, 56, 72)→8 × 5 = 40 ≠ 56; 8 × 6 = 48 ≠ 72 Second option: (6, 36, 48)→6 × 5 = 30 ≠ 36; 6 × 6 = 36 ≠ 48 Third option: (9, 45, 54)→9 × 5 = 45; 9 × 6 = 54 Fourth option: (12, 60, 48)→12 × 5 = 60; 12 × 6 = 72 ≠ 48
So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.
Question : Directions: Select the option figure in which the given figure is embedded (rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of the question figure with all the option figures, it is evident that the given question figure is embedded only in the fourth option figure.
Hence, the fourth option is correct.
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 164, 172, 145, ?, 84
Option 1: 209
Option 2: 308
Option 3: 283
Option 4: 234
Correct Answer: 209
Solution : Given: 164, 172, 145, ?, 84
Add and subtract the cube of the consecutive natural numbers (starting from 2) alternatively from the previous term to get the next term in the series.
So, 209 is the missing term in the series. Hence, the first option is correct.
Question : The radius of a circle is 1.75 cm. What is the circumference of the circle? (Take $\pi=\frac{22}{7}$)
Option 1: 5.5 cm
Option 2: 11 cm
Option 3: 9.63 cm
Option 4: 22 cm
Correct Answer: 11 cm
Solution : Given: The radius of a circle = 1.75 cm Circumference of the circle = $2\pi r=2\times\frac{22}{7}\times 1.75=44 × 0.25=11\ \text{cm}$ Hence, the correct answer is 11 cm.
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. South Korea is the most cosmetically (1)______ country on Earth. Beauty editors estimate that it is because of the government’s heavy investment (2)______ industry. It is ahead of its competitors, and its citizens (3)_____ twice as much on skincare products as consumers in the United States, the UK, and France.

Question: Select the most appropriate option to fill in the blank number 1.
Option 1: ancient
Option 2: primitive
Option 3: advanced
Option 4: early
Correct Answer: advanced
Solution : The third option is the correct answer.
The word cosmetically suggests that the blank should be filled with an adjective that describes the level of development or sophistication in the field of cosmetics. Advanced is an adjective that fits well in this context, indicating that South Korea is the most advanced country in terms of cosmetics.
Therefore, the right word to fill in the blank is advanced.
