Question Discussion & Solution

The correct answer is Ramgarh.

Key Points

• Ramgarh Gas Thermal Power Station (RGTPP)-
  • Ramgarh Gas Thermal Power Station is the first gas thermal power plant of Rajasthan.
  • The first unit was commissioned on dated 15 November 1994 AD.
  • Location - Ramgarh, Jaisalmer
  • The present capacity of the plant is 270.50 MW.

Additional Information

• Dholpur Combined Cycle Power Plant is also a Gas Thermal Plant of Rajasthan with a capacity of 330 MW.
• Giral Thermal Power Plant is a lignite coal-based power project in Giral, Barmer.
• Chhabra Thermal Power Plant has 6 operational units with a capacity of 2320 MW.

LAN :

• LAN stands for Local Area Network.
• It's a group of computers which belong to the same organisation, and are linked within a small geographic area using a network using the same technology (Ethernet).
• E.g. Wi-Fi

MAN :

• MANs (Metropolitan Area Networks) connect multiple geographically nearby LANs to one another at high speeds.
• A MAN lets two remote nodes communicate as if they were part of the same local area network.
• E.g. microwave antenna on a TV news van, extended high in the air, beaming video and sound back to the main TV studio.

WAN:

• A WAN (Wide Area Network or extended network) connects multiple LANs to one another over great geographic distances.
• WANs operate using routers, which can "choose" the most appropriate path for data to take to reach a network node.
• E.g.: Internet

PAN:

• A personal area network (PAN) is a network used for data transmission amongst devices such as computers, telephones, tablets, personal digital assistants, fax machines and printers, that are located close to a single user

E.g. Bluetooth

The correct answer is Wheat.

Key Points

Concept-

• A wide range of fungal, bacterial, and viral pathogens, affect the yield of cultivated crop species, especially in tropical climates.
• Crop losses can often be significant, up to 20-30 per cent, or sometimes even total.
• In this situation, the breeding and development of cultivars resistant to disease enhance food production.
• This also helps reduce the dependence on the use of fungicides and bacteriocides.

Explanation-

• Resistance of the host plant is the ability to prevent the pathogen from causing disease and is determined by the genetic constitution of the host plant.
• Before breeding is undertaken, it is important to know about the causative organism and the mode of transmission.
• Some of the diseases caused by-
  • Fungi are rusts, e.g., brown rust of wheat, red rot of sugarcane, and late blight of potato.
  • Bacteria – black rot of crucifers.
  • Viruses – tobacco mosaic, turnip mosaic, etc.
• Brown rust of wheat is caused by the fungus Puccinia triticina.

Therefore the brown rust is the disease of wheat.

Additional Information

• Red rot is the disease of sugarcane.
• Late blight is the disease of potatoes.
• Mosaic virus is the disease of turnip.

The correct answer is Output.

Key Points

• Output devices allow us to receive information from the computer.
• An output device is any hardware device used to send data from a computer to another device or user.
• Examples of output devices are-
  • monitors and projectors (video), headphones and speakers (audio), or printers and plotters (physical reproduction in the form of text or graphics).
