Rakesh Sharma became the first Indian to travel to space on April 2, 1984, as part of the Soviet Intercosmos program. He flew aboard Soyuz T-11 to the Salyut 7 space station.

Kalpana-1 was India's first dedicated meteorological satellite, launched in 2002. It provided weather monitoring and cyclone warning services. Options A and D are incorrect - Kalpana-1 was neither a spaceship nor a lunar mission. Option B (geosynchronous) is also incorrect; while it was in geostationary orbit, its primary classification was meteorological, not just a communication satellite.

Parsley is widely recognized as a natural remedy for garlic breath due to its high chlorophyll content, which acts as a natural deodorizer. The enzymes in parsley help neutralize sulfur compounds in garlic that cause persistent odor. While other herbs like basil and sage have strong flavors, parsley is specifically known for this breath-freshening property.

Column A simplifies to sqrt((z²-4)²) = |z²-4|, which is the absolute value of Column B. When z²-4 ≥ 0 (i.e., |z| ≥ 2), both columns are equal. When z²-4 < 0 (i.e., -2 < z < 2), Column A equals 4-z² which is positive, while Column B is negative. Since the relationship changes based on z's value, it cannot be determined universally.

Tamarind is the essential souring agent that gives both sambar and rasam their characteristic tangy flavor. While sambar contains multiple spices including fenugreek, the defining sour taste comes from tamarind pulp. Sugar would make these dishes sweet, which is incorrect. Garlic is sometimes added but is not the essential ingredient.

JRD Tata (Jehangir Ratanji Dadabhoy Tata) received both the Bharat Ratna (India's highest civilian award) and the UN Population Award in 1992. He was honored for his pioneering contributions to Indian industry and his support for family planning and population control initiatives. Ratan Tata is his successor, while Ratanji Dadabhoy Tata was his father and Sir Dorab Tata was his uncle.

G. Madhavan Nair served as Chairman of ISRO from 2003 to 2009, overseeing missions like Chandrayaan-1. K. Kasturirangan (option A, misspelled) was his predecessor. A. P. J. Abdul Kalam was a former ISRO chairman but not current in the exam's timeframe. Rakesh Sharma is a cosmonaut, not ISRO chairman.

Even numbers between 1 and n are 2, 4, 6, ..., (n-1). Sum = 2+4+6+...+(n-1) = 2(1+2+3+...+(n-1)/2). Number of terms = (n-1)/2. Sum = 2 × [(n-1)/2 × ((n-1)/2 + 1)] / 2 = (n-1)/2 × (n+1)/2 = (n²-1)/4. Given (n²-1)/4 = 79×80, so n²-1 = 31680, n² = 31681, n = 177. But wait - let's recalculate: sum of first k even numbers = k(k+1). Here k = (n-1)/2, so sum = (n-1)/2 × (n+1)/2 = 79×80. Solving: (n²-1)/4 = 6320, n²-1 = 25280, n² = 25281, n = 159.

Total balls = 3+4+2 = 9. First draw (red): P(Red) = 3/9 = 1/3. Ball is replaced, so still 9 balls. Second draw (white): P(White) = 2/9. P(Red then White) = (1/3) × (2/9) = 2/27. But the question asks for red AND white in any order. P(White then Red) = (2/9) × (1/3) = 2/27. Total = 2/27 + 2/27 = 4/27. Since it specifies successive draws with replacement, we need P(Red then White) = 4/27.
