Writing task 1(Line graph)
The line graph illustrates how people consumed fast food in UK per week over a course of 20 years starting from 1970.
Overall, as can be seen clearly that there was a significant increase in Fish & Chips's and Hamburger's consumption. While Pizza witnessed a modest decline over the timescale which made up the highest consumption at first.
Looking at the details, in 1970, the consumption of Pizza was the most, at over 300 grams per week, which was more than more 200 grams that of Fish & Chips and was over 6 times as much as Hamburger's one. However, time registered a slight decrease in the consumption of Pizza, with just more than 200 grams being eaten per week.
On the other hand, it was over 2 decades later that the figure for Fish & Chips overtook Pizza's and then became a new dominant fast food type, at 500 grams per week in 1990. After that was the number for hamburger which also experienced a sharp increase, at around 300 grams at the end of examined period.
