plz help I will make u brainleist!!why is the use demand of professionals in the field of agriculture explain.​

Answers

Answer:The field of agriculture over the years had continued to develop, with more and more people leaving the industry for other jobs elsewhere. This has led it to reach a point whereby the industry can no longer sustain this, and now needs more labour. Originally, agriculture had been knows to be a very hard and labour intensive job, with long working hours and poor conditions, this has led to many people in the last few decades leave the industry, and further had led to the new generation being reluctant to join the industry. This therefore has led to their shortage of labour. In most developing countries, machines and other specialized equipment does most of the work on a farm, however machines just can’t do everything, that’s where humans come in. So the demand for agricultural workers had risen as a result of people leaving the industry, and agriculture has become one of the most promising carrerrs, run high pay, and decent living conditions. I hope this helped.

Answers

Answer:

1- A dispute between Rome and Carthage over the island of Sicily.

2- A Roman fleet badly defeated Carthage's navy off the coast of Sicily.

3- Hannibal defeated the Romans at the Battle of Cannae in southern Italy.

4- In 146 BC Rome finally destroyed Carthage and controlled a large portion of the Mediterranean region. Shortly thereafter, Rome started to control parts of Asia.

Explanation:

The Punic Wars were the wars between Carthage and the Roman Republic, which came into conflict when their expansionist interests met in the western half of the Mediterranean.

The First Punic War took place between 264 and 241 BC, mainly in Sicily. During this conflict, Rome annexed Sicily to its territories, thus obtaining control of the center of the Mediterranean Sea.

The Second Punic War, which occurred between 218 and 201 BC, took place mainly on the Italian and Iberian Peninsula. On the European continent Hannibal Barca inflicted serious defeats on the Romans, but after the Roman invasion of North Africa, Carthage was finally defeated.

Finally, the Third Punic War occurred between 149 and 146 BC. This war was a three-year siege of Carthage by the Romans and ended with the capture and total destruction of the city, definitively consolidating Rome's control of the Mediterranean.

Arms control became one of Gorbachev's top priorities.

Explanation:

Mikhail Gorbachev had a very different idea about arms control in SSSR and his policies on the matter did not follow the previous ideas. Soviet ideas were focused on having the advance against the US in various fields, including the military.

However, Gorbachev started rethinking the goals and approaches. He called for the nuclear weapons treaty. He wanted to completely ban nuclear weapons and arms, as he found them to be immoral and something that must not be used in the military conflict.

This significantly changed not only the relationship between the Soviet Union and the US but complete SSSR foreign policy.
