Article: TB infection begins when the mycobacteria reach the pulmonary alveoli, where they invade and replicate within endosomes of alveolar macrophages. Macrophages identify the bacterium as foreign and attempt to eliminate it by phagocytosis. During this process, the bacterium is enveloped by the macrophage and stored temporarily in a membrane-bound vesicle called a phagosome. The phagosome then combines with a lysosome to create a phagolysosome. In the phagolysosome, the cell attempts to use reactive oxygen species and acid to kill the bacterium. However, M. tuberculosis has a thick, waxy mycolic acid capsule that protects it from these toxic substances. M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell.

Question: What vesicle is the temporary holding room for the M. tuberculosis bacterium during phagocytosis?
Ans: phagosome


Here is a question about this article: There are two broad categories of public funding, direct, which entails a monetary transfer to a party, and indirect, which includes broadcasting time on state media, use of the mail service or supplies. According to the Comparative Data from the ACE Electoral Knowledge Network, out of a sample of over 180 nations, 25% of nations provide no direct or indirect public funding, 58% provide direct public funding and 60% of nations provide indirect public funding. Some countries provide both direct and indirect public funding to political parties. Funding may be equal for all parties or depend on the results of previous elections or the number of candidates participating in an election. Frequently parties rely on a mix of private and public funding and are required to disclose their finances to the Election management body.
What is the answer to this question: Are parties required to reveal their funding?
****
So... required to disclose their finances to the Election management body.


The problem: Answer a question about this article:
Monastic reform became an important issue during the 11th century, as elites began to worry that monks were not adhering to the rules binding them to a strictly religious life. Cluny Abbey, founded in the Mâcon region of France in 909, was established as part of the Cluniac Reforms, a larger movement of monastic reform in response to this fear. Cluny quickly established a reputation for austerity and rigour. It sought to maintain a high quality of spiritual life by placing itself under the protection of the papacy and by electing its own abbot without interference from laymen, thus maintaining economic and political independence from local lords.
Along with rigor, what did Cluny have a reputation for?
****
The answer: austerity


Problem: Please answer a question about the following article about The Sun (United Kingdom):
On 6 February 2015, it was announced that Judge Richard Marks is to be replaced by Judge Charles Wide at the retrial. Two days earlier, Marks had emailed counsel for the defendants telling them: "It has been decided (not by me but by my elders and betters) that I am not going to be doing the retrial". Reporting the decision in UK newspaper The Guardian, Lisa O’Carroll wrote: "Wide is the only judge so far to have presided in a case which has seen a conviction of a journalist in relation to allegations of unlawful payments to public officials for stories. The journalist, who cannot be named for legal reasons, is appealing the verdict". Defence counsel for the four journalists threatened to take the decision to judicial review, with the barrister representing Pharo, Nigel Rumfitt QC, saying: "The way this has come about gives rise to the impression that something has been going on behind the scenes which should not have been going on behind the scenes and which should have been dealt with transparently". He added that the defendants were "extremely concerned" and "entitled" to know why Marks was being replaced by Wide.
In which newspaper did Lisa O'Carroll report the choice of judge?
A: The Guardian

Through the use of multidimensional scaling, psychologists can map out similar emotional experiences, which allows a visual depiction of the "emotional distance" between experiences. A further step can be taken by looking at the map's dimensions of the emotional experiences. The emotional experiences are divided into two dimensions known as valence (how negative or positive the experience feels) and arousal (how energized or enervated the experience feels). These two dimensions can be depicted on a 2D coordinate map. This two-dimensional map was theorized to capture one important component of emotion called core affect. Core affect is not the only component to emotion, but gives the emotion its hedonic and felt energy.

What do psychologists use to visually map emotional experiences?
Answer: multidimensional scaling


Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.
How much copper is estimated to exsist on earth?
1014 tons
