Question

What were the advantages of the invention of refrigerated ships?
a. This reduced the shipping cost and lowered meat prices in Europe.
b. The poor in Europe could now consume a more varied diet.
c. To the earlier, monotony of bread and potatoes many, not all could add meat, butter or egg.
d. All of the above.

Answer 1

Hint:
- Boats designed as fishing and/or fish processing vessels, but also capable of holding frozen cargo, are fish factory vessels.
- Intentionally, freezers or main frozen goods carriers are designed to hold frozen cargo.

Complete step by step solution:

What?
A reefer ship is a refrigerated cargo ship, usually used to transport perishable goods such as fruit, meat , fish, vegetables , dairy products and other items that require temperature-controlled transport.

When invented ?
- In 1901, the first refrigerated vessels specially built for the transport of bananas appeared, such as the Port Morant. To decrease the temperature and regulate it, CO2 machines were then used. This was a decisive step forward for the transport of fruits responsive to temperature.
- By 1869, from Indianola, Texas, to New Orleans, Louisiana, reefers were exporting beef carcasses frozen in a salt-ice mixture to be served in hospitals, hotels and restaurants. When Northam sailed in 1876 from Australia to the UK, the first attempt was made to ship refrigerated beef.

Advantages –
1. This decreased shipping costs and lowered Europe's meat prices.
2. A more diverse diet would now be eaten by the poor in Europe.
3. Some, not all, might add beef, butter or egg to the earlier monotony of bread and potatoes.
4. Social harmony within the nation and support for imperialism abroad were encouraged by better living conditions.


Hence, the correct answer is option D.

Note:
Although a reefer may have an internal refrigeration unit, they depend on external power at a land-based location, a container ship or on a quay from electrical power points ('reefer points'). Air cooling eliminates the heat produced by the reefers, while water cooling helps to reduce the heat generated by the reefers., That’s how a refrigerated ship works.
