Problem: Charleston, South Carolina:

The community was established by several shiploads of settlers from Bermuda (which lies due east of South Carolina, although at 1,030 km or 640 mi, it is closest to Cape Hatteras, North Carolina), under the leadership of governor William Sayle, on the west bank of the Ashley River, a few miles northwest of the present-day city center. It was soon predicted by the Earl of Shaftesbury, one of the Lords Proprietors, to become a "great port towne", a destiny the city quickly fulfilled. In 1680, the settlement was moved east of the Ashley River to the peninsula between the Ashley and Cooper Rivers. Not only was this location more defensible, but it also offered access to a fine natural harbor.

Problem: Iran:

The 1960s was a significant decade for Iranian cinema, with 25 commercial films produced annually on average throughout the early 60s, increasing to 65 by the end of the decade. The majority of production focused on melodrama and thrillers. With the screening of the films Kaiser and The Cow, directed by Masoud Kimiai and Dariush Mehrjui respectively in 1969, alternative films established their status in the film industry. Attempts to organize a film festival that had begun in 1954 within the framework of the Golrizan Festival, bore fruits in the form of the Sepas Festival in 1969. The endeavors also resulted in the formation of the Tehran World Festival in 1973.
