In the previous class you studied a sample report. Reread the sample report and then answer the question below. From Bar Charts Basics: The bar chart illustrates the income generated by tourism in Egypt in certain years between 1982 and 2003. Overall, there was a higher income from tourism at the end of the period than at the beginning with an increase in income from 1982 to 2000 followed by a decline. In 1982, income from tourism stood at the lowest amount of the whole period at roughly 0.3 billion dollars. Between 1982 and the year 2000, income from tourism in Egypt increased significantly. In 1993 it increased by 1.5 billion dollars to approximately 1.8 billion. 2 years later the figure stood at 2.3 billion and in a further 2 years it was just below 3 billion dollars. Income from tourism reached a peak in 2000 at around 4.3 billion dollars. In 2001 income from tourism dropped slightly to 3.8 billion dollars and it remained stable at this level in the following year. In 2003 there was a significant drop in the contribution of tourism as it fell from 3.8 billion to the same level as in 1993 at roughly 1.8 billion dollars. How is this task report structured?
