Article: This changed with the recent sovereign-debt crisis. The ECB always could, and through the late summer of 2011 did, purchase bonds issued by the weaker states even though it assumes, in doing so, the risk of a deteriorating balance sheet. ECB buying focused primarily on Spanish and Italian debt. Certain techniques can minimise the impact. Purchases of Italian bonds by the central bank, for example, were intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank.

Question: What debt did the ECB focus on abtaining?
Ans: Spanish and Italian

Article: One significant feature of the Premier League in the mid-2000s was the dominance of the so-called "Big Four" clubs: Arsenal, Chelsea, Liverpool and Manchester United. During this decade, and particularly from 2002 to 2009, they dominated the top four spots, which came with UEFA Champions League qualification, taking all top four places in 5 out of 6 seasons from 200304 to 200809 inclusive, with Arsenal going as far as winning the league without losing a single game in 200304, the only time it has ever happened in the Premier League. In May 2008 Kevin Keegan stated that "Big Four" dominance threatened the division, "This league is in danger of becoming one of the most boring but great leagues in the world." Premier League chief executive Richard Scudamore said in defence: "There are a lot of different tussles that go on in the Premier League depending on whether you're at the top, in the middle or at the bottom that make it interesting."

Question: Which of the "Big Four" teams did not lose a single game in the 2003-04 season?
Ans: Arsenal

Article: In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species. The use of scents is especially well known to have developed in social insects.:96105

Question: The chemicals used by insects to communicate are called what?

semiochemicals
