Article: Even though most ethnic groups prefer to communicate in their own languages, English as the official language is widely used for education, business transactions and for official purposes. English as a first language is used only by a small minority of the country's urban elite, and it is not spoken at all in some rural areas. Hausa is the most widely spoken of the 3 main languages spoken in Nigeria itself (Igbo, Hausa and Yoruba) but unlike the Yorubas and Igbos, the Hausas tend not to travel far outside Nigeria itself.[citation needed]

Problem: Please answer a question about the following article about Mexico City:
The World Bank has sponsored a project to curb air pollution through public transport improvements and the Mexican government has started shutting down polluting factories. They have phased out diesel buses and mandated new emission controls on new cars; since 1993 all new cars must be fitted with a catalytic converter, which reduces the emissions released. Trucks must use only liquefied petroleum gas (LPG). Also construction of an underground rail system was begun in 1968 in order to help curb air pollution problems and alleviate traffic congestion. Today it has over 201 km (125 mi) of track and carries over 5 million people every day. Fees are kept low to encourage use of the system and during rush hours the crush is so great, that authorities have reserved a special carriage specifically for women. Due to these initiatives and others, the air quality in Mexico City has begun to improve, with the air becoming cleaner since 1991, when the air quality was declared to be a public health risk for 355 days of the year.[citation needed]
When did the underground rail system begin construction?
A: 1968


Question: Read this and answer the question

Lilius's proposals had two components. Firstly, he proposed a correction to the length of the year. The mean tropical year is 365.24219 days long. As the average length of a Julian year is 365.25 days, the Julian year is almost 11 minutes longer than the mean tropical year. The discrepancy results in a drift of about three days every 400 years. Lilius's proposal resulted in an average year of 365.2425 days (see Accuracy). At the time of Gregory's reform there had already been a drift of 10 days since the Council of Nicaea, resulting in the vernal equinox falling on 10 or 11 March instead of the ecclesiastically fixed date of 21 March, and if unreformed it would drift further. Lilius proposed that the 10-day drift should be corrected by deleting the Julian leap day on each of its ten occurrences over a period of forty years, thereby providing for a gradual return of the equinox to 21 March.

On what date was the original vernal equinox set?
Answer: 21 March


There is a project involving the future relocation of Plymouth City Council's headquarters, the civic centre, to the current location of the Bretonside bus station; it would involve both the bus station and civic centre being demolished and a rebuilt together at the location with the land from the civic centre being sold off.

Millbay is being regenerated with mixed residential, retail and office space alongside the ferry port.
What city region is located near a ferry terminal?
Millbay
