(a) Voyager-2

(b) New Horizons

(c) Lisa Pathfinder

(d) Evolved LISA

Answer: (d) Evolved LISA

Explanation: Evolved LISA (Laser Interferometer Space Antenna) is a space-based gravitational wave observatory developed by ESA with contributions from NASA.

educationprovince.com

Explanation: GL-10 is a remotely piloted plane similar to an Unmanned Aerial Vehicle (UAV). It is designed and developed in such a way that it can take off like a helicopter and fly like an airplane. It is a battery-powered 10-engine with a wingspan of 3.05 meters. Eight electric motors are mounted on the wings. 2 electric motors are mounted on the tail. It weighs a maximum of 28.1 kilograms at takeoff. Due to its versatile vertical takeoff and landing ability, it produces less noise. It can be used as a UAV for small package delivery or vertical takeoff and landing, as well as long-endurance surveillance for agriculture, mapping, and other applications. Its modified scaled-up version can be used as a persons air vehicle.

Q5 [2015]: The term ‘Goldilocks Zone’ is often seen in the news in the context of:

(a) The limits of habitable zone above the surface of the Earth

(b) Regions inside the Earth where shale gas is available

(c) Search for the Earth-like planets in outer space

(d) Search for meteorites containing precious metals

Answer: (c) Search for the Earth-like planets in outer space

Explanation: The Goldilocks Zone is the livable zone around a star where the temperature is not too hot and not too cold for liquid water to exist on a planet. It is a metaphor for the childrens story Goldilocks and the Three Bears, in which a young girl selects from sets of three objects, eschewing the extremes (such as those that are enormous or small, hot or cold) and fixing on the one that is just right in the middle. The Goldilocks zone of the Sun surrounds the Earth. All of Earths water would freeze if it were found where the dwarf planet Pluto is; however, all of Earths water would boil out if it were found where Mercury is.
