the graph below shows predictions about the numbers of people who will study three major world languages between 2020 and 2030 summarise the information by selecting and reporting the main features and make comparisons where relevant

The given chart illustrates the number of learners studying English, Spanish, and Mandarin from 2020 to 2030.
As can be seen from the chart, all the quantities of three languages learnt by students increased in the period of ten years. Another noticeable point is that the figures in the Mandarin and English sectors witnessed the most dramatic change.
In 2020, while there are only 100 million learners who studied Mandarin, the number of students learning Spanish is about 200 million, about two times the figure in the Mandarin sector. In addition, the quantity of students practising English is 550 million. It is clear that English massively used all over the world is an international language.
From 2020 onwards, both the numbers of learners of Mandarin and Spanish grew moderately by 200 million and 100 million respectively and reached the 300 million students point in 2024 before the figures in Mandarin and Spanish sectors fluctuated from 300 million to 350 million. After that, while the number of students learning Spanish rose slightly, a notable raise of 250 million was recorded in the number of learners of Mandarin. Meanwhile, the quantity of English students witnessed a 150 million growth in the first four years, declining slightly in the next two years and then went up sharply and reached the top at the end of the period.
