Please hurry❗️❗️❤️ Describe the new techniques during the Song Dynasty which led to increased farming

- "early ripening rice"

- new irrigation techniques and systems

- planting new crops (cotton, tea)

Explanation:

Song Dynasty was a famous Chinese dinasty ruling from 10th till 13th century.

Among other things, this period is famous for massive agricultural improvements which increased crop production. Subsequently, that led to the increase in China's population.

Probably the most famous improvement was the development and use of "early ripening rice". This rice had a shorter life cycle which meant that it could grow 2 - 3 times per year, making more crops.

Also, new irrigation systems and techniques were invented which allowed the crops to be watered more efficiently and preventing drought.

We must not forget that China started farming other crops at that time including tea and cotton.

All of this improved farming making it one of the most notable legacy of the Song Dynasty.

Explanation:

C) Some prefixes are added to the end of a root word.

Explanation:

Prefixes are letters that are added to the beginning of a root word in order to create a word that has a different meaning. Therefore, by adding a prefix, we change one word into another one. Knowing the meaning of a prefix can help us figure out the meaning of the new word. For example, if we know that "un-" means "the opposite," then we can better understand what "unhappy" (not happy), "unable" (not able) and unpack (the opposite of packing) mean. However, prefixes are always added at the beginning of the word. When letter are added to the end of the word, these are called suffixes.
