Using the information in the graph and write a report. Write 120-140 words. 2021/3/27 * $ million 2021/3/27 * The graph shows the fluctuation in a company’s sales to South Asia over a period of twelve months. According to the graph, sales to South Asia increased steadily from 7 million dollars in January to 10 million dollars in May. After this, sales fell dramatically, hitting the lowest point in June at 6 million dollars. There was then a slight increase in July. Between July and September sales stayed constant at a little over 6 million dollars. There was then a sharp rise between September and November with a peak of 11 million dollars in November. After November sales declined significantly to 8 million dollars. 2021/3/27 * Sample 2 Question 1: The two graphs indicate the effect of two biocides: GE and HI, used to purify the polluted water during the five months. Using the information from the graphs, write a short report comparing the situation when two brands of biocides are applied with the situation without the treatment. Write 120-140 words on the separate answer paper provided. ? 2021/3/27 * 2021/3/27 * 2021/3/27 * The two graphs compare the effect of two biocides: GE and HI. Without the treatment, the purity degrees of the polluted water drop to less than 20% after five months. The effect of the GE treatment is reasonably sound. As the purity degree of water without treatment falls to 35% after three months, the one with GE biocides is shown to be as pure as 70% at that time. After five months, the purity degree of the treated water still maintains 40%. In contrast, the effect of the HI biocide treatment is unsatisfactory. Althoug
