Questions and Solutions

Q.1A

Which two of the following extreme locations are connected by the east-west corridor?
  1. Mumbai and Nagpur
  2. Silcher and Porbandar
  3. Mumbai and Kolkata
  4. Nagpur and Siligudi
Solution: The East-West corridor is a significant transportation project in India designed to enhance connectivity across the country. It stretches from the westernmost point to the easternmost point. Specifically, this corridor connects Silchar in the state of Assam in the east to Porbandar in the state of Gujarat in the west. Therefore, the correct option is Silcher and Porbandar.

Q.1B

Which mode of transportation reduces trans-shipment losses and delays?
  1. Railways
  2. Roadways
  3. Pipeline
  4. Waterways
Solution: The mode of transportation that significantly reduces trans-shipment losses and delays, particularly for the transport of liquids and gases, is the pipeline. Unlike other modes that require loading and unloading goods multiple times, pipelines allow for continuous flow, minimizing handling costs and preventing spoilage or loss of contents. This makes them highly efficient for specific types of cargo.

Q.1C

Which one of the following states is not connected with the H.V.J. pipeline?
  1. Madhya Pradesh
  2. Maharashtra
  3. Gujarat
  4. Uttar Pradesh
Solution: The H.V.J. pipeline, which stands for Hazira-Vijaypur-Jagdishpur, is a crucial natural gas pipeline network in India. This pipeline originates from Hazira in Gujarat, passes through Vijaypur in Madhya Pradesh, and extends to Jagdishpur near Delhi, serving Uttar Pradesh. It also has branches connecting to other areas. The states directly connected by this pipeline network include Gujarat, Madhya Pradesh, Rajasthan, Haryana, and the National Capital Territory (NCT) of Delhi. Maharashtra is not directly served by the main H.V.J. pipeline route.

Q.1D

Which one of the following ports is the deepest land-locked and well protected port along the east coast?
  1. Chennai
  2. Paradip
  3. Tuticorin
  4. Vishakhapatnam
Solution: Vishakhapatnam port, located in Andhra Pradesh on the east coast of India, is distinguished as the deepest land-locked and well-protected natural harbour. It is situated in a sheltered bay, protected by a rocky spur projecting into the sea. Its depth allows it to handle large vessels, making it a strategically important port for India's maritime trade.

Q.1E

Which one of the following is the most important mode of transportation in India?
  1. Pipeline
  2. Railways
  3. Roadways
  4. Airways
Solution: Roadways are considered the most important and popular mode of transportation in India. They are the cheapest and most accessible form of transport, connecting even remote areas. Roadways carry a substantial proportion of both passenger and freight traffic, playing a vital role in the country's economy and daily life.

Q.1F
