Correct Answer: b) Comet

Explanation:

Comets are celestial objects that are primarily composed of ice, dust, and rocky material. They are known for their highly elongated elliptical orbits around the Sun. This means that their paths are stretched out and not circular. Due to this elongated orbit, comets spend most of their time far away from the Sun in the outer regions of the solar system. However, when they approach the Sun during their orbit, the heat causes the ice in the comet to vaporize, creating a glowing coma (a cloud of gas and dust) and sometimes a visible tail that points away from the Sun.

In contrast:
– Asteroids generally have more circular or slightly elliptical orbits and are mostly found in the asteroid belt between Mars and Jupiter.
– Meteorites are fragments of meteoroids that survive their passage through Earth’s atmosphere and land on Earth’s surface.
– Meteors are meteoroids that burn up upon entering Earth’s atmosphere, creating a streak of light in the sky.

Thus, comets are the celestial objects with highly elongated elliptical orbits.

Correct Answer: c) Sarwa Hitahishi

Explanation:

The first Hindi daily newspaper to be published in Bihar was Sarwa Hitahishi. It was launched in 1874 and played a significant role in promoting Hindi journalism in the region.

Correct Answer: b) Iron ore

Explanation:
Minas Gerais is a state in Brazil that is renowned for its rich mineral resources, particularly iron ore. It is one of the largest producers of iron ore in the world, with extensive mining operations in the region. The state is home to the Quadrilátero Ferrífero (Iron Quadrangle), which is a major iron ore mining area.

Other minerals like bauxite, mica, and coal are also found in various parts of the world, but they are not specifically associated with Minas Gerais in the same way as iron ore. Hence, the correct answer is iron ore.

The correct answer is Option B: a, b, and d are correct.

Explanation:

a) Makhali Gosala was indeed the most important leader of the Ajivika sect. He was a contemporary of Mahavira (the 24th Tirthankara of Jainism) and Gautama Buddha. He is considered the founder of the Ajivika sect.

b) The central idea of the Ajivika philosophy was “Niyati,” which means fate or destiny. They believed that everything in life is predetermined and governed by fate, leaving no room for free will or human effort.

c) The statement about discrimination on the basis of caste and class is incorrect. The Ajivikas did not promote caste or class discrimination. In fact, they were known for their egalitarian approach, rejecting the rigid caste system prevalent in society at that time.

d) The Ajivikas had regular sabhas (meetings) for discussions and gatherings. This was a part of their organizational structure and community practices.

Thus, statements a, b, and d are correct, making Option B the right choice.

The correct answer is Option B: Plasma.

Explanation: Blood is composed of two main components: the fluid part and the cellular part. The fluid part of the blood is called plasma, which makes up about 55% of the total blood volume. Plasma is a yellowish liquid that primarily consists of water (about 90-92%), along with proteins, electrolytes, nutrients, hormones, and waste products. It serves as the medium for transporting nutrients, hormones, and waste products throughout the body.

The other components mentioned in the options are part of the cellular portion of blood:
– WBC (White Blood Cells): These are responsible for fighting infections and are part of the immune system.
– Blood platelets: These are involved in blood clotting to prevent excessive bleeding.
– RBC (Red Blood Cells): These carry oxygen to the body’s tissues and remove carbon dioxide.

Thus, the fluid part of the blood is plasma.

The correct answer is:

Option C: Gandhiji during Quit India Movement

Explanation: The slogan “Do or Die” was given by Mahatma Gandhi during the Quit India Movement in 1942. This movement was launched on August 8, 1942, at the Bombay session of the All-India Congress Committee. Gandhi urged Indians to fight for complete independence from British rule and encouraged them to act with determination, even if it meant sacrificing their lives. The slogan symbolized the resolve to achieve freedom at any cost.

The correct answer is: Option D: Credit Guarantee Fund Trust for Micro and Small Enterprises

Explanation: CGTMSE stands for Credit Guarantee Fund Trust for Micro and Small Enterprises. It is a trust established by the Government of India and the Small Industries Development Bank of India (SIDBI) to provide credit guarantees to financial institutions for loans given to micro and small enterprises. This initiative aims to promote and support the growth of small businesses by reducing the risk for lenders and encouraging them to provide loans without requiring collateral.

The correct answer is Option B: Tc (Technetium).

Explanation: Technetium (Tc) is the first artificially prepared element. It was discovered in 1937 by Carlo Perrier and Emilio Segrè. Technetium does not occur naturally on Earth in significant amounts because all its isotopes are radioactive and have relatively short half-lives, meaning they decay over time. It was created artificially by bombarding molybdenum atoms with deuterons (a type of hydrogen nucleus) in a cyclotron. This discovery marked the first time an element was synthesized in a laboratory, making Technetium the first artificially prepared element.

Answer: b) Narmada

Explanation:
The Narmada River is different from the others because of its unique geographical and flow characteristics. Here’s why:

1. Narmada River:
– It flows westward into the Arabian Sea, which is uncommon for Indian rivers as most major rivers in India flow eastward into the Bay of Bengal.
– It originates from the Amarkantak Plateau in Madhya Pradesh and flows through a rift valley between the Vindhya and Satpura ranges.

2. Other Rivers:
– Tungabhadra, Penganga, and Mahanadi are all east-flowing rivers that drain into the Bay of Bengal.
– Tungabhadra is a tributary of the Krishna River.
– Penganga is a tributary of the Godavari River.
– Mahanadi is a major river flowing through Odisha and Chhattisgarh, emptying into the Bay of Bengal.

Thus, the Narmada River stands out due to its westward flow and its geological setting, making it different from the others.
