The graph below shows the amounts of waste produced by three companies over a period of 15 years.

The line graph illustrates how much

waste

was generated by three enterprises, namely Companies A,

B

, and

C

over a 15-year period starting from 2000 to 2015. It is noticeable that the amount of

waste

produced by company

C

registered dramatic upward trends,

while

that of companies A and

B

witnessed completely an opposite trajectory during the surveyed period. Company

C

, notably, was by far the most important

waste

generation in the final year From the outset of 2000,

waste

production by group A was the highest prevalence, accounting for exactly 12

tons

, which was in the region of 4 tonnes higher than

waste

output in firm

B

. After that, there was a remarkable decline to nearly 11 tonnes in the figure for organization A in 2005, whilst a sharp increase to around 10

tons

was witnessed in the statistics of company

B

at the same time.

Subsequently

, both saw sharp decreases, with roughly 8 tonnes and precisely 3

tons

respectively in 2015. Commencing from 2000, approximately 4

tons

of

waste

output came from team

C

, hitting the lowest point in 2000, after which it went up sharply to almost 7

tons

in 2010 before reaching its peak of more or less 10

tons

, accounting for the first rank in

waste

generation in the final year
