The bar chart compares the oil production capacity of six Gulf countries (Iran, Iraq, Kuwait, Qatar, Saudi Arabia, and the UAE) in 1990, 2000, 2005, and 2010.

Overall, Saudi Arabia had by far the highest oil production capacity throughout the period, while Qatar produced the least. Most countries saw only slight increases, but Saudi Arabia experienced a significant growth between 1990 and 2010.

In 1990, Saudi Arabia produced around 8 million barrels per day, much more than any other country. Iran and the UAE followed, each at about 3 million barrels daily, while Iraq, Kuwait, and Qatar all produced under 2 million barrels.

By 2010, Saudi Arabia’s production had risen dramatically to about 14 million barrels per day, remaining the dominant producer. Iran and the UAE both increased modestly to around 4 million barrels, and the other three countries also experienced small rises of about 1 million barrels compared to 1990.

In summary, although all Gulf countries increased their oil output over the 20-year period, Saudi Arabia’s production grew the most and continued to account for the majority of total oil capacity.

The two pie charts compare the ways in which staff and students travelled to university in 2004 and 2009.

Overall, travelling by car was the most popular method in both years, while the percentage of people using buses increased noticeably over the period. In contrast, the proportion of car users decreased.

In 2004, more than half of the staff and students (51%) travelled by car, making it the most common form of transport. Buses were the second most popular at 27%, followed by bicycles (9%), trains (4%) and walking (15%).

By 2009, the percentage of people travelling by car had fallen significantly to 28%. Meanwhile, the proportion of bus users rose sharply to 46%, becoming the main form of transport to university. The share of those who walked dropped slightly to 6%, and the figures for bicycles and trains remained relatively small at around 7% and 4%, respectively.

In summary, while the car was the main mode of transport in 2004, buses became the most popular way to travel to university by 2009, suggesting a shift towards public transport.
