Trucking a. is the least used transportation mode for manufacturing goods. b. is one of the least flexible transportation modes. c. is increasingly using computers to manage its operations. d. does not play a role in multimodal shipping.

The answer is: C) is increasingly using computers to manage its operations.

Explanation:

Not only truck transportation companies are using computers to manage their operations, almost very single business is using computers in its operations.

Trains and trucks are the most common land transportation modes for manufacturing products.

The main advantage of trucks over railroad system is the flexibility of trucks. While railroad transportation is cheaper, you always need a railroad. While trucks can go almost anywhere as long as a road exists.

Trucks play a vital role in multimodal shipping. Multimodal shipping includes trucks, railroad, air freight and ships. For example a truck is used to move a container form the factory to the railroad yard. Then the railroad transport the container to the ship. Then the ship carries the container to Europe. Once there, a truck takes the container to a wholesale distributor.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
