Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
The map of earthquake intensity published by CEA after surveying 500,000 km2 of the affected area shows a maximum liedu of XI on the China Seismic Intensity Scale (CSIS), described as "very destructive" on the European Macroseismic Scale (EMS) from which CSIS drew reference. (USGS, using the Modified Mercalli intensity scale (CC), also placed maximum intensity at XI, "very disastrous".) Two south-west-north-east stripes of liedu XI are centered around Yingxiu, Wenchuan (the town closest to the epicenter of the main quake) and Beichuan (the town repeatedly struck by strong aftershocks including one registering MS 6.1 on Aug 1, 2008), both in Sichuan Province, occupying a total of 2,419 km2. The Yingxiu liedu-XI zone is about 66 km long and 20 km wide along WenchuanDujiangyanPengzhou; the Beichuan liedu-XI zone is about 82 km long and 15 km wide along An CountyBeichuanPingwu. The area with liedu X (comparable to X on EMS, "destructive" and X on MM, "disastrous") spans 3,144 km2. The area affected by earthquakes exceeding liedu VI totals 440,442 km2, occupying an oval 936 km long and 596 km wide, spanning three provinces and one autonomous region.
What was the intensity scaled at?
A: XI
Problem: Please answer a question about the following article about Gramophone record:
The phonograph disc record was the primary medium used for music reproduction until late in the 20th century, replacing the phonograph cylinder recordwith which it had co-existed from the late 1880s through to the 1920sby the late 1920s. Records retained the largest market share even when new formats such as compact cassette were mass-marketed. By the late 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the vinyl record left the mainstream in 1991. From the 1990s to the 2010s, records continued to be manufactured and sold on a much smaller scale, and were especially used by disc jockeys (DJ)s, released by artists in some genres, and listened to by a niche market of audiophiles. The phonograph record has made a niche resurgence in the early 21st century 9.2 million records were sold in the U.S. in 2014, a 260% increase since 2009. Likewise, in the UK sales have increased five-fold from 2009 to 2014.
Approximately how many phonograph records were sold in 2014?
A: 9.2 million
Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
The central government estimates that over 7,000 inadequately engineered schoolrooms collapsed in the earthquake. Chinese citizens have since invented a catch phrase: "tofu-dregs schoolhouses" (Chinese: ), to mock both the quality and the quantity of these inferior constructions that killed so many school children. Due to the one-child policy, many families lost their only child when schools in the region collapsed during the earthquake. Consequently, Sichuan provincial and local officials have lifted the restriction for families whose only child was either killed or severely injured in the disaster. So-called "illegal children" under 18 years of age may be registered as legal replacements for their dead siblings; if the dead child was illegal, no further outstanding fines would apply. Reimbursement would not, however, be offered for fines that were already levied.
Why did so many schools collapse during the earthquake?
A: inadequately engineered
Problem: Please answer a question about the following article about Alloy:
Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.
Precipitation hardening alloys are sometimes also?
A:
heat-treatable alloys
