Final answer:
The word 'yet' correctly completes the sentence by introducing a contrast to the previous statement about Hartford. Hartford's history of economic growth contrasts with its present socio-economic disparities, including high poverty rates and urban blight.
Step-by-step explanation:
The correct word to complete the sentence 'Hartford is a rich city, but suffers from many symptoms of urban blight' is yet. This is because 'yet' is often used to introduce a contrast that is unexpected in light of the first part of the sentence. The other options, 'however', 'so', and 'and', are also words that might indicate contrast or addition, but 'yet' is the most appropriate in the context of this sentence structure. Exploring Hartford's history, we see that its economic growth was initially spurred by its strategic location, which facilitated the establishment of insurance companies and other businesses. Despite Hartford's economic achievements, stark contrasts exist, such as high poverty rates and urban blight, which underline the complex socio-economic issues within cities. Issues like gentrification and unstable housing significantly affect urban environments, leading to a widening gap between the rich and the poor and the disenfranchisement of some residents. This echoes a common urban dilemma of socio-economic disparities in cities that once thrived on industrial and financial success but presently grapple with urban decay and inequality.
