He became the first human to step onto the lunar surface, famously saying, "That's one small step for man, one giant leap for mankind." His historic achievement marked a major milestone in space exploration. Other options (for context) Aldrin: Refers to Buzz Aldrin, the second man to walk on the Moon, who accompanied Armstrong on Apollo 11. Michael Collins: The third member of the Apollo 11 crew, who orbited the Moon in the command module but did not land. Gagarin: Refers to Yuri Gagarin, the first human to travel into space in 1961, but he never landed on the Moon.

Question 1688

Which of the following is not an element ?

AOxygen

BNitrogen

CHydrogen

DMarble

Show answer

D. MarbleMarble is not an element; it is a metamorphic rock composed primarily of calcium carbonate (CaCO₃). It forms when limestone is subjected to high pressure and temperature, causing recrystallization. Being a compound and mixture of minerals, marble does not consist of a single type of atom, unlike elements. Other options (for context) Oxygen (O₂): A chemical element essential for respiration and combustion. Nitrogen (N₂): A chemical element that makes up about 78% of Earth’s atmosphere. Hydrogen (H₂): The lightest chemical element and the main component of stars.

Question 1683

When Lunar Eclipse occurs ?

AWhen Sun is between Earth and Moon

BWhen Earth is between Sun and Moon

CWhen Moon is between Earth and Sun

DWhen Earth is between Sun and other celestial bodies.

Show answer

B. When Earth is between Sun and MoonA Lunar Eclipse occurs when the Earth comes between the Sun and the Moon, causing the Earth’s shadow to fall on the Moon. This alignment blocks the sunlight that normally reflects off the Moon’s surface, making it appear dark or reddish (known as a Blood Moon). Lunar eclipses only occur during a full moon when the Sun, Earth, and Moon are in a straight line (or nearly so). Other options (for context) When Sun is between Earth and Moon: Incorrect — this alignment causes no eclipse. When Moon is between Earth and Sun: This alignment causes a solar eclipse, not a lunar one. When Earth is between Sun and other celestial bodies: Too general — lunar eclipse specifically involves the Moon.

Question 1682

What is Air Quality Index ?

AIt tells about sound pollution.

BIt measures air pollution mainly sulphur content in the air.

CIt measures ozone levels in the selected area.

DIt checks the colour of the air.

Show answer

C. It measures ozone levels in the selected area.The Air Quality Index (AQI) is a numerical scale used to measure and report the quality of air in a particular area. It primarily indicates the level of air pollution and its potential impact on human health. The AQI is calculated based on concentrations of key air pollutants — including ozone (O₃), particulate matter (PM₂.₅ and PM₁₀), nitrogen dioxide (NO₂), sulphur dioxide (SO₂), and carbon monoxide (CO). Higher AQI values indicate poorer air quality and greater health risks. Other options (for context) It tells about sound pollution: Incorrect — AQI is unrelated to noise levels. It measures air pollution mainly sulphur content in the air: Partly true, but AQI includes multiple pollutants, not just sulphur dioxide. It checks the colour of the air: Inc

Question 1681

Who among the following is considered as the father of artificial intelligence ?

ACharles Babbage

BLee De Forest

CJohn McCarthy

DJ. P. Eckert

Show answer

C. John McCarthyJohn McCarthy is regarded as the father of Artificial Intelligence (AI). He coined the term “Artificial Intelligence” in 1956 during the Dartmouth Conference, which is considered the founding event of AI as a research field. McCarthy also developed the LISP programming language, one of the earliest languages used for AI programming. His contributions laid the foundation for modern AI research, machine learning, and robotics. Other options (for context) Charles Babbage: Known as the “Father of the Computer” for designing the Analytical Engine. Lee De Forest: Invented the triode vacuum tube, which advanced early electronics. J. P. Eckert: Co-inventor of ENIAC, one of the first electronic general-purpose computers.
