Input: Article: Discrete transistors are individually packaged transistors. Transistors come in many different semiconductor packages (see image). The two main categories are through-hole (or leaded), and surface-mount, also known as surface-mount device (SMD). The ball grid array (BGA) is the latest surface-mount package (currently only for large integrated circuits). It has solder "balls" on the underside in place of leads. Because they are smaller and have shorter interconnections, SMDs have better high-frequency characteristics but lower power rating.

Now answer this question: What is a ball grid array composed of?

Output: solder "balls" on the underside in place of leads


Article: East Tucson is relatively new compared to other parts of the city, developed between the 1950s and the 1970s,[citation needed] with developments such as Desert Palms Park. It is generally classified as the area of the city east of Swan Road, with above-average real estate values relative to the rest of the city. The area includes urban and suburban development near the Rincon Mountains. East Tucson includes Saguaro National Park East. Tucson's "Restaurant Row" is also located on the east side, along with a significant corporate and financial presence. Restaurant Row is sandwiched by three of Tucson's storied Neighborhoods: Harold Bell Wright Estates, named after the famous author's ranch which occupied some of that area prior to the depression; the Tucson Country Club (the third to bear the name Tucson Country Club), and the Dorado Country Club. Tucson's largest office building is 5151 East Broadway in east Tucson, completed in 1975. The first phases of Williams Centre, a mixed-use, master-planned development on Broadway near Craycroft Road, were opened in 1987. Park Place, a recently renovated shopping center, is also located along Broadway (west of Wilmot Road).

Question: What park was developed between the 1950's and 1970's?

According to Asian Times, sworn in as the "Beijing Olympic Games Sacred Flame Protection Unit" during a ceremony in August 2007, their main job is to keep the Olympic flame alight throughout the journey and to assist in transferring the flame between the torches, the lanterns and the cauldrons. They wear matching blue tracksuits and are intended to accompany the torch every step of the way. One of the torch attendants, dubbed "Second Right Brother," has developed a significant online fan-base, particularly among China's female netizens.
What is the answer to this question: How many attendants accompanied the flame during it's travels?
****
So... 30

One of the league's early success stories was the Detroit Drive. A primary team for some of the AFL's most highly regarded players, including George LaFrance and Gary and Alvin Rettig, as well as being a second career chance for quarterback Art Schlichter, the Drive regularly played before sold out crowds at Joe Louis Arena, and went to the ArenaBowl every year of their existence (1988–1993). The AFL's first dynasty came to an end when their owner, Mike Ilitch (who also owned Little Caesars Pizza and the Detroit Red Wings) bought the Detroit Tigers baseball team and sold the AFL team.
In what year did the Drive go to their first Arena Bowl?
****
The answer: 1988


Problem: Please answer a question about the following article about Web browser:
In 1993, browser software was further innovated by Marc Andreessen with the release of Mosaic, "the world's first popular browser", which made the World Wide Web system easy to use and more accessible to the average person. Andreesen's browser sparked the internet boom of the 1990s. The introduction of Mosaic in 1993 – one of the first graphical web browsers – led to an explosion in web use. Andreessen, the leader of the Mosaic team at National Center for Supercomputing Applications (NCSA), soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which quickly became the world's most popular browser, accounting for 90% of all web use at its peak (see usage share of web browsers).
What browser did Andreessen release in 1994?
A: Netscape Navigator
