Problem: BeiDou Navigation Satellite System:

In 2007, the official Xinhua News Agency reported that the resolution of the BeiDou system was as high as 0.5 metres. With the existing user terminals it appears that the calibrated accuracy is 20m (100m, uncalibrated).

There are no terminals, but the calibration accuracy is still what?

Problem: Florida:

The United States Census Bureau estimates that the population of Florida was 20,271,272 on July 1, 2015, a 7.82% increase since the 2010 United States Census. The population of Florida in the 2010 census was 18,801,310. Florida was the seventh fastest-growing state in the U.S. in the 12-month period ending July 1, 2012. In 2010, the center of population of Florida was located between Fort Meade and Frostproof. The center of population has moved less than 5 miles (8 km) to the east and approximately 1 mile (1.6 km) to the north between 1980 and 2010 and has been located in Polk County since the 1960 census. The population exceeded 19.7 million by December 2014, surpassing the population of the state of New York for the first time.

Problem: Department store:

Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).

What types of stores have created even more competition?
---
A: superstores

Problem: Catalan language:

In gender inflection, the most notable feature is (compared to Portuguese, Spanish or Italian), the loss of the typical masculine suffix -o. Thus, the alternance of -o/-a, has been replaced by /-a. There are only a few exceptions, like minso/minsa ("scarce"). Many not completely predictable morphological alternations may occur, such as:

What is the usual masculine suffix?
