Problem: Among Richmond's most interesting architectural features is its Cast-iron architecture. Second only to New Orleans in its concentration of cast iron work, the city is home to a unique collection of cast iron porches, balconies, fences, and finials. Richmond's position as a center of iron production helped to fuel its popularity within the city. At the height of production in the 1890, 25 foundries operated in the city employing nearly 3,500 metal workers. This number is seven times the number of general construction workers being employed in Richmond at the time which illustrates the importance of its iron exports. Porches and fences in urban neighborhoods such as Jackson Ward, Church Hill, and Monroe Ward are particularly elaborate, often featuring ornate iron casts never replicated outside of Richmond. In some cases cast were made for a single residential or commercial application.
Along with Jackson and Monroe Wards, what neighborhood notably features cast-iron fences?

Answer: Church Hill

Problem: In September 2008, the crisis hit its most critical stage. There was the equivalent of a bank run on the money market funds, which frequently invest in commercial paper issued by corporations to fund their operations and payrolls. Withdrawal from money markets were $144.5 billion during one week, versus $7.1 billion the week prior. This interrupted the ability of corporations to rollover (replace) their short-term debt. The U.S. government responded by extending insurance for money market accounts analogous to bank deposit insurance via a temporary guarantee and with Federal Reserve programs to purchase commercial paper. The TED spread, an indicator of perceived credit risk in the general economy, spiked up in July 2007, remained volatile for a year, then spiked even higher in September 2008, reaching a record 4.65% on October 10, 2008.
The equivalent of a bank run on which funds occurred in September 2008?
---
Answer: money market funds

Problem: An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to a high temperature, by passing an electric current through it, until it glows with visible light (incandescence). The hot filament is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated. In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life. The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections.
Which type of light bulb uses inert gas?
---
Answer:
incandescent light bulb
