Problem: Please answer a question about the following article about Plymouth:
During the English Civil War Plymouth sided with the Parliamentarians and was besieged for almost four years by the Royalists. The last major attack by the Royalist was by Sir Richard Grenville leading thousands of soldiers towards Plymouth, but they were defeated by the Plymothians at Freedom Fields Park. The civil war ended as a Parliamentary win, but monarchy was restored by King Charles II in 1660, who imprisoned many of the Parliamentary heroes on Drake's Island. Construction of the Royal Citadel began in 1665, after the Restoration; it was armed with cannon facing both out to sea and into the town, rumoured to be a reminder to residents not to oppose the Crown. Mount Batten tower also dates from around this time.

Problem: Please answer a question about the following article about Incandescent light bulb:
On 13 December 1904, Hungarian Sandor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for a tungsten filament lamp that lasted longer and gave brighter light than the carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries. Filling a bulb with an inert gas such as argon or nitrogen retards the evaporation of the tungsten filament compared to operating it in a vacuum. This allows for greater temperatures and therefore greater efficacy with less reduction in filament life.
Which inventors patented the tungsten filament lamp?
A: Hungarian Sandor Just and Croatian Franjo Hanaman
