Plymouth railway station, which opened in 1877, is managed by Great Western Railway and also sees trains on the CrossCountry network. Smaller stations are served by local trains on the Tamar Valley Line and Cornish Main Line. First Great Western have come under fire recently, due to widespread rail service cuts across the south-west, which affect Plymouth greatly. Three MPs from the three main political parties in the region have lobbied that the train services are vital to its economy.

Input: Article: The concept of nobility flourished in New Spain in a way not seen in other parts of the Americas. Spaniards encountered a society in which the concept of nobility mirrored that of their own. Spaniards respected the indigenous order of nobility and added to it. In the ensuing centuries, possession of a noble title in Mexico did not mean one exercised great political power, for one's power was limited even if the accumulation of wealth was not. The concept of nobility in Mexico was not political but rather a very conservative Spanish social one, based on proving the worthiness of the family. Most of these families proved their worth by making fortunes in New Spain outside of the city itself, then spending the revenues in the capital, building churches, supporting charities and building extravagant palatial homes. The craze to build the most opulent residence possible reached its height in the last half of the 18th century. Many of these palaces can still be seen today, leading to Mexico City's nickname of "The city of palaces" given by Alexander Von Humboldt.

Now answer this question: When did the construction of exuberant houses slow down?

Output: the last half of the 18th century

Article: High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully at the other antenna. An example of a high-gain antenna is a parabolic dish such as a satellite television antenna. Low-gain antennas have shorter range, but the orientation of the antenna is relatively unimportant. An example of a low-gain antenna is the whip antenna found on portable radios and cordless phones. Antenna gain should not be confused with amplifier gain, a separate parameter measuring the increase in signal power due to an amplifying device.

Question: What type of antenna would be best if placement was tricky?
Ans: Low-gain

Here is a question about this article: The discipline of plant ecology was pioneered in the late 19th century by botanists such as Eugenius Warming, who produced the hypothesis that plants form communities, and his mentor and successor Christen C. Raunkir whose system for describing plant life forms is still in use today. The concept that the composition of plant communities such as temperate broadleaf forest changes by a process of ecological succession was developed by Henry Chandler Cowles, Arthur Tansley and Frederic Clements. Clements is credited with the idea of climax vegetation as the most complex vegetation that an environment can support and Tansley introduced the concept of ecosystems to biology. Building on the extensive earlier work of Alphonse de Candolle, Nikolai Vavilov (18871943) produced accounts of the biogeography, centres of origin, and evolutionary history of economic plants.
What is the answer to this question: What did Warming believe that plants can do?
****
So... form communities

The problem: Answer a question about this article:
Fortaleza del Cerro overlooks the bay of Montevideo. An observation post at this location was first built by the Spanish in the late 18th century. In 1802, a beacon replaced the observation post; construction of the fortress began in 1809 and was completed in 1839. It has been involved in many historical developments and has been repeatedly taken over by various sides. In 1907, the old beacon was replaced with a stronger electric one. It has been a National Monument since 1931 and has housed a military museum since 1916. Today it is one of the tourist attractions of Montevideo.
What overlooks the bay of Montevideo?
