input: Make use of the article to answer the questions. Rome, Italy (CNN) -- A Nigerian man who sang in a Vatican choir arranged gay liaisons for an Italian government official who served in the unpaid role of papal usher, according to transcripts of wiretaps collected by Italian authorities. 

The wiretaps were gathered as part of an investigation into how public-works contracts were awarded. 

The purported conversations were between Angelo Balducci, who oversaw the Italian government's awarding of construction contracts -- including work on the airport at Perugia -- and Thomas Chinedu Ehiem, a 39-year-old Nigerian singer. They were recorded between April 14, 2008, and January 20, 2010. 

In addition to working for the government, Balducci served as a "gentleman of his holiness," also known as a papal usher or "Vatican gentleman." The main responsibility of the ceremonial position is to welcome heads of state to the Vatican and escort them to see the Pope. 

Balducci is one of three public officials who, along with a businessman, have been jailed on charges related to corruption in the public works department. The public officials are alleged to have awarded contracts to businessmen who offered them favors, money, sex, and/or house remodeling in exchange. The suspects, who deny the charges, are in "cautionary custody" though they have not been charged or indicted. 

The Italian news media have nicknamed the scandal "grande opere," which translates as "big works." The transcripts of the wiretaps were made public on Wednesday and widely disseminated in the media. 

Balducci's lawyer, Franco Coppi, lambasted investigators' handling of his client.  1. What is the name of the Nigerian performer?

input: The law of the United States comprises many levels of codified and uncodified forms of law, of which the most important is the United States Constitution, the foundation of the federal government of the United States. The Constitution sets out the boundaries of federal law, which consists of acts of Congress, treaties ratified by the Senate, regulations promulgated by the executive branch, and case law originating from the federal judiciary. The United States Code is the official compilation and codification of general and permanent federal statutory law. 

Federal law and treaties, so long as they are in accordance with the Constitution, preempt conflicting state and territorial laws in the 50 U.S. states and in the territories. However, the scope of federal preemption is limited because the scope of federal power is not universal. In the dual-sovereign system of American federalism (actually tripartite because of the presence of Indian reservations), states are the plenary sovereigns, each with their own constitution, while the federal sovereign possesses only the limited supreme authority enumerated in the Constitution. Indeed, states may grant their citizens broader rights than the federal Constitution as long as they do not infringe on any federal constitutional rights. Thus, most U.S. law (especially the actual "living law" of contract, tort, property, criminal, and family law experienced by the majority of citizens on a day-to-day basis) consists primarily of state law, which can and does vary greatly from one state to the next. 1.

Q: The term high definition once described a series of television systems originating from August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true "HDTV" spanned the entire 20th century, as each new system became more HD than the last.In the beginning of the 21st century, this race has continued with 4k, 5k and current 8K systems. 

The British high-definition TV service started trials in August 1936 and a regular service on 2 November 1936 using both the (mechanical) Baird 240 line sequential scan (later to be inaccurately rechristened 'progressive') and the (electronic) Marconi-EMI 405 line interlaced systems. The Baird system was discontinued in February 1937. In 1938 France followed with their own 441-line system, variants of which were also used by a number of other countries. The US NTSC 525-line system joined in 1941. In 1949 France introduced an even higher-resolution standard at 819 lines, a system that should have been high definition even by today's standards, but was monochrome only and the technical limitations of the time prevented it from achieving the definition of which it should have been capable. All of these systems used interlacing and a 4:3 aspect ratio except the 240-line system which was progressive (actually described at the time by the technically correct term "sequential") and the 405-line system which started as 5:4 and later changed to 4:3. The 405-line system adopted the (at that time) revolutionary idea of interlaced scanning to overcome the flicker problem of the 240-line with its 25 Hz frame rate. The 240-line system could have doubled its frame rate but this would have meant that the transmitted signal would have doubled in bandwidth, an unacceptable option as the video baseband bandwidth was required to be not more than 3 MHz.

Answer the following questions:
1. What can't the video baseband bandwidth be more than?
2. Whose high-definition TV service first started trials?
3. When?
4. When did regular service start?
5. What did high definition originally describe?
6. How many lines of resolution did they have?
7. What drove companies and nations to create true HDTV?
8. How long did that competition last?
9. What is the most current system?
10. What was one of the previous systems in this race?
11. Whas the Baird 240 scan mechanical or electrical?
12. What was it wrongly known as?
13. Which system was electronic?
14. How many lines did it have?
