Consider the following statements regarding Oort cloud:
- The Oort cloud is the most distant region of our solar system.
- It is like a big, thick-walled bubble made of icy pieces of space debris.
- The Oort cloud is believed to be a giant spherical shell surrounding the rest of the solar system.
Which of the statements given above is/are correct?
CorrectSolution: D
The Oort Cloud is the most distant region of our solar system. Even the nearest objects in the Oort Cloud are thought to be many times farther from the Sun than the outer reaches of the Kuiper Belt.
Unlike the orbits of the planets and the Kuiper Belt, which lie mostly in the same flat disk around the Sun, the Oort Cloud is believed to be a giant spherical shell surrounding the rest of the solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud might contain billions, or even trillions, of objects.
Home of Comets
Because the orbits of long-period comets are so extremely long, scientists suspect that the Oort Cloud is the source of most of those comets. For example, comet C/2013 A1 Siding Spring, which made a very close pass by Mars in 2014, will not return to the inner solar system for about 740,000 years.

Consider the following statements regarding Aquaponics
- The method combines aquaculture with hydroponics.
- The difference between aquaponics and hydroponics is that synthetic fertilizers are used in hydroponics for providing nutrients to plants.
Which of the statements given above is/are correct?
CorrectSolution: C
Aquaponics
- The method combines aquaculture — cultivating fish and other aquatic animals in tanks with organic inputs — with hydroponics, where plants are cultivated in water.
- The water from the fish tank is pumped onto the beds where plants grow.
- While the fish excretions provide nutrients for the plants (hence no chemical fertilizers are needed), the clean water is recirculated back to the fish tank.
- While the initial cost to set up the facility would be high, the recurring cost is low in aquaponics.
- The difference between aquaponics and hydroponics is that synthetic fertilisers are used in hydroponics for providing nutrients to plants and hence cultivation of fish is not possible in hydroponics.
