QUES: Between 64 and 104 major aftershocks, ranging in magnitude from 4.0 to 6.1, were recorded within 72 hours of the main quake. According to Chinese official counts, "by 12:00 CST, November 6, 2008 there had been 42,719 total aftershocks, of which 246 ranged from 4.0 MS to 4.9 MS, 34 from 5.0 MS to 5.9 MS, and 8 from 6.0 Ms to 6.4 MS; the strongest aftershock measured 6.4 MS." The latest aftershock exceeding M6 occurred on August 5, 2008.
When were the aftershocks recorded?

ANS: within 72 hours of the main quake.

QUES: In 1979, the Japanese state broadcaster NHK first developed consumer high-definition television with a 5:3 display aspect ratio. The system, known as Hi-Vision or MUSE after its Multiple sub-Nyquist sampling encoding for encoding the signal, required about twice the bandwidth of the existing NTSC system but provided about four times the resolution (1080i/1125 lines). Satellite test broadcasts started in 1989, with regular testing starting in 1991 and regular broadcasting of BS-9ch commencing on November 25, 1994, which featured commercial and NHK programming.
When did satellite test broadcasts of lo-Vision start?

ANS: unanswerable

QUES: In 1409, a hospital was founded and placed under the patronage of Santa Maria de los Inocentes; to this was attached a confraternity devoted to recovering the bodies of the unfriended dead in the city and within a radius of three miles (4.8 km) around it. At the end of the 15th century this confraternity separated from the hospital, and continued its work under the name of "Cofradia para el amparo de los desamparados". King Philip IV of Spain and the Duke of Arcos suggested the building of the new chapel, and in 1647 the Viceroy, Conde de Oropesa, who had been preserved from the bubonic plague, insisted on carrying out their project. The Blessed Virgin was proclaimed patroness of the city under the title of Virgen de los desamparados (Virgin of the Forsaken), and Archbishop Pedro de Urbina, on 31 June 1652, laid the cornerstone of the new chapel of this name. The archiepiscopal palace, a grain market in the time of the Moors, is simple in design, with an inside cloister and a handsome chapel. In 1357, the arch that connects it with the cathedral was built. In the council chamber are preserved the portraits of all the prelates of Valencia.
What was the confraternity called after its separation from the hospital?

ANS: Cofradia para el amparo de los desamparados

QUES: Another effective way to decrease the transmission rate of infectious diseases is to recognize the effects of small-world networks. In epidemics, there are often extensive interactions within hubs or groups of infected individuals and other interactions within discrete hubs of susceptible individuals. Despite the low interaction between discrete hubs, the disease can jump to and spread in a susceptible hub via a single or few interactions with an infected hub. Thus, infection rates in small-world networks can be reduced somewhat if interactions between individuals within infected hubs are eliminated (Figure 1). However, infection rates can be drastically reduced if the main focus is on the prevention of transmission jumps between hubs. The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method. Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001.
What is a way of drastically reducing infection rates?

ANS:
focus is on the prevention of transmission jumps
