List-I	List-II
A. The bird that never makes its nest	1. Lizard
B. The animal that shakes off its tail	2. Chimpanzee
C. Largest living creature	3. Cuckoo
D. Most intelligent animal	4. Blue whale

	A	B	C	D

(b)	3	1	4	2
(c)	4	3	2	1
(d)	1	2	3	4

Correct Answer: (b)

Solution:The cuckoo never makes its nest. Lizard can give up its tail with the mere touch and tail again regenerate because it has horizontal division in their vertebrals. Chimpanzee is said to be most wisest animal and blue whale is the largest living creature.

42. Which State Government launched the State-Level Committee for Vulture Conservation (SLCVC), proposed by the national action for the protection of vultures in India? [69th B.P.S.C. (Pre) 2023]

(a) Tamil Nadu
(b) Sikkim
(c) Assam
(d) Meghalaya

Correct Answer: (a) Tamil Nadu

Solution:In October, 2022 Government of Tamil Nadu launched the State-Level Committee for Vulture Conservation (SLCVC) for coordination between various wings of the government to implement the Action Plan for Vulture Conservation (APVC) 2020-2025.

43. Ten captive-bred Asian Giant Tortoises (Manouria emys), one of the largest tortoise species in mainland Asia, were recently released into which National Park of India? [69th B.P.S.C. (Pre) 2023]

(a) Ntangki National Park
(b) Periyar National Park
(c) Pench National Park
(d) Khangchendzonga National Park

Correct Answer: (a) Ntangki National Park

Solution:Ten captive-bred Asian Giant Tortoises (Manouria emys), one of the largest tortoise species in mainland Asia, were released in December, 2022 into a protected area of Ntangki National Park of Nagaland. The rewilding process was carried out with the assistance of the Turtle Survival Alliance (TSA) and the Wildlife Conservation Society India (WCSI).

The Asian Giant Tortoise is listed as "critically endangered" on the International Union for Conservation of Nature's Red List of Threatened Species. Over-exploitation and unsustainable use by local communities have pushed the species to the brink of extinction. In December of last year, the TSA and Creative Conservation Alliance released ten captive-bred individuals in the Matamuhuri valley of Bangladesh.

44. Consider the following animals of India: [I.A.S. (Pre) 2003]

Crocodile
Elephant

Which of these is/are endangered species?

(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2

Correct Answer: (c) Both 1 and 2

Solution:According to the Red Data List of International Union for Conservation of Nature (IUCN) crocodile species found in India are in critically endangered category while Indian elephant is in endangered category. The rewilding process was carried out with the assistance of the Turtle Survival Alliance (TSA) and the Wildlife Conservation Society India (WCSI).

45. About whom is said ‘India’s large wild cats’, which became extinct in India? [R.A.S./R.T.S. (Pre) 1992]

(a) Cheetah
(b) Leopard
(c) Tiger
(d) Lion

Correct Answer: (a) Cheetah

Solution:Cheetah also known as the ‘hunting leopard’, became extinct in India. Government of India initiated a programme to re-introduce cheetahs to India after they became locally extinct more than 70 years ago. In 2022, as a part of ‘Project Cheetah’, cheetahs flown in from Namibia and South Africa were introduced to Kuno National Park in India.

46. The term ‘Sixth mass extinction/sixth extinction’ is often mentioned in the news in the context of the discussion of [I.A.S. (Pre) 2018]

(a) Widespread monoculture practices in agriculture and large-scale commercial farming with indiscriminate use of chemicals in many parts of the world that may result in the loss of good native ecosystems.
(b) Fears of a possible collision of a meteorite with the Earth in the near future in the manner it happened 65 million years ago that caused the mass extinction of many species including those of dinosaurs.
(c) Large scale cultivation of genetically modified crops in many parts of the world and promoting their cultivation in other parts of the world which may cause the disappearance of good native crop plants and the loss of food biodiversity.
(d) Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change

Correct Answer: (d) Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change

Solution:During the past 500 million years, there were five ‘mass extinctions’ during which many species rapidly died. Now scientists warn that the sixth mass extinction of life on Earth is unfolding more quickly than feared and humans are the primary cause, who are pursuing a ‘biological annihilation’ that is coming faster than feared. According to a study published in journal ‘Science’ in July, 2017 the planet is on the verge of witnessing sixth mass extinction phase. Previous mass extinctions were due to natural climate changes, huge volcanic eruptions or catastrophic meteor strikes. But the one is due to human activities such as deforestation, overpopulation, pollution, poaching and extreme weather events tied to man-caused global warming, the study said.

47. Which one of the following is not properly matched? [U.P.P.C.S (Pre) 2010]

(a) Gene splicing and Recombinant DNA technology - Genetic Engineering
(b) A diagnostic test to detect the presence or absence of genetic disorders in unborn child - Amniocentesis
(c) A process by which living organisms break down complex matter into simpler constituents - Biodegradation
(d) An inbuilt time keeping system in all organisms - Biomass

Correct Answer: (d) An inbuilt time keeping system in all organisms - Biomass

Solution:

Biomass is biological material derived from living organisms. It most often refers to plants or plant-based materials which are specifically called lignocelluloses biomass. As an energy source, biomass can either be used directly via combustion to produce heat or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into thermal, chemical and biochemical methods. Remaining pairs are correctly matched.

48. Diseases of inner parts of the human body are diagnosed through: [U.P.P.C.S. (Mains) 2014]

(a) Cardiograph
(b) Endoscope
(c) Gyroscope
(d) Cresograph

Correct Answer: (b) Endoscope

Solution:Endoscopy is a nonsurgical procedure used to examine a person’s digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, the doctor can view a picture of digestive tract on a T.V. monitor.

Endoscopy doesn't require any cutting or incisions, making it a minimally invasive procedure. The endoscope allows doctors to see the lining of the digestive tract, looking for any abnormalities like ulcers, inflammation, or growths.

There are different types of endoscopy depending on which part of the digestive tract is being examined, such as upper endoscopy (esophagus and stomach), colonoscopy (colon), or sigmoidoscopy (lower colon). Endoscopy can be used to diagnose digestive disorders, but it can also be used to treat conditions, such as removing polyps or taking biopsies.

49. An endoscope is a - [U.P.P.C.S. (R.I.) 2014]

(a) Narrow telescope
(b) Type of camera
(c) Simple microscope
(d) None of these

Correct Answer: (b) Type of camera

Solution:An endoscope is a medical device consisting of a long, thin, flexible (or rigid) tube which has a light source and a video camera. Images of the inside of the patient’s body can be seen on a screen. It is not suitable to categorize endoscope as a type of camera.

50. Which of the following types is used by Computed Tomography employed for visualisation of the internal structure of human body? [I.A.S. (Pre) 2007]

(a) X-rays
(b) Sound waves
(c) Magnetic resonance
(d) Radio-isotopes

Correct Answer: (a) X-rays

Solution:An X-ray computed tomography (X-ray CT) or computerized axial tomography scan (CAT scan), makes use of computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual 'slices') of specific areas of a scanned object, allowing the user to see inside the object without cutting.
