Dubai, one of the seven emirates that form the UAE, has a very high proportion of immigrants who account for more than 80 percent of its population. The city has been witnessing a massive growth in the construction sector fuelled by a very high demand for rental space in the city. This in turn led to an impressive increase in the availability of new rental property in Dubai. A substantial downward pressure was thus created on rental rates which declined by more than 50 percent earlier this year. With supply far exceeding the demand, industry analysts had earlier predicted a sharper fall in rental rates, given the construction boom. Which of the following, if true, can explain why rental rates in Dubai did not decline further? A. Low rents have attracted many foreign firms, increasing overseas clients' demand for housing. B. Rental rates in Abu Dhabi, located just 74 miles away, were even lower than those in Dubai. C. The recent recession caused a substantial increase in unemployment in Dubai. D. The UAE still has over $50 billion worth of infrastructure projects in the pipeline. E. Construction projects in the UAE have rarely faced any financial bottlenecks
