Input: Article: As they grew older Madonna and her sisters would feel deep sadness as the vivid memory of their mother began drifting farther from them. They would study pictures of her and come to think that she resembled poet Anne Sexton and Hollywood actresses. This would later raise Madonna's interest in poetry, with Sylvia Plath being her favourite. Later, Madonna commented: "We were all wounded in one way or another by [her death], and then we spent the rest of our lives reacting to it or dealing with it or trying to turn into something else. The anguish of losing my mom left me with a certain kind of loneliness and an incredible longing for something. If I hadn't had that emptiness, I wouldn't have been so driven. Her death had a lot to do with me saying—after I got over my heartache—I'm going to be really strong if I can't have my mother. I'm going to take care of myself." Taraborrelli felt that in time, no doubt because of the devastation she felt, Madonna would never again allow herself, or even her daughter, to feel as abandoned as she had felt when her mother died. "Her death had taught [Madonna] a valuable lesson, that she would have to remain strong for herself because, she feared weakness—particularly her own—and wanted to be the queen of her own castle."

Now answer this question: Who felt that her mother death was the driving force behind her success?

Output: Madonna


Article: Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.

Question: Besides wear, what is a downside of stiff brush springs?
Ans: lower efficiency


Here is a question about this article: Modern Estonian orthography is based on the Newer Orthography created by Eduard Ahrens in the second half of the 19th century based on Finnish orthography. The Older Orthography it replaced was created in the 17th century by Bengt Gottfried Forselius and Johann Hornung based on standard German orthography. Earlier writing in Estonian had by and large used an ad hoc orthography based on Latin and Middle Low German orthography. Some influences of the standard German orthography — for example, writing 'W'/'w' instead of 'V'/'v' persisted well into the 1930s.
What is the answer to this question: From what other country's orthography did the Older Orthography get its basis?
****
So... standard German orthography


The problem: Answer a question about this article:
Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 15.8% of the country's gross domestic product. According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America). Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. Mexico City is the greatest contributor to the country's industrial GDP (15.8%) and also the greatest contributor to the country's GDP in the service sector (25.3%). Due to the limited non-urbanized space at the south—most of which is protected through environmental laws—the contribution of the Federal District in agriculture is the smallest of all federal entities in the country. Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020.
What percentage of service sector national GDP does Mexico City account for?
****
The answer: 25.3


Problem: Please answer a question about the following article about Elizabeth II:
The Suez crisis and the choice of Eden's successor led in 1957 to the first major personal criticism of the Queen. In a magazine, which he owned and edited, Lord Altrincham accused her of being "out of touch". Altrincham was denounced by public figures and slapped by a member of the public appalled by his comments. Six years later, in 1963, Macmillan resigned and advised the Queen to appoint the Earl of Home as prime minister, advice that she followed. The Queen again came under criticism for appointing the prime minister on the advice of a small number of ministers or a single minister. In 1965, the Conservatives adopted a formal mechanism for electing a leader, thus relieving her of involvement.
Aside from her choice of Eden's successor, what crisis caused Elizabeth to be criticized?
A: Suez crisis


Question: Read this and answer the question

The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.

What invaders are causing changes along the North American Atlantic coast?
Answer:
lion fish
