Here is a question about this article: To minimize overall weight and size, miniature PM motors may use high energy magnets made with neodymium or other strategic elements; most such are neodymium-iron-boron alloy. With their higher flux density, electric machines with high-energy PMs are at least competitive with all optimally designed singly-fed synchronous and induction electric machines. Miniature motors resemble the structure in the illustration, except that they have at least three rotor poles (to ensure starting, regardless of rotor position) and their outer housing is a steel tube that magnetically links the exteriors of the curved field magnets.
What is the answer to this question: How do PMs rate against other types of electric motors?
****
So... least competitive

Here is a question about this article: Natural theology was not a unified doctrine, and while some such as Louis Agassiz were strongly opposed to the ideas in the book, others sought a reconciliation in which evolution was seen as purposeful. In the Church of England, some liberal clergymen interpreted natural selection as an instrument of God's design, with the cleric Charles Kingsley seeing it as "just as noble a conception of Deity". In the second edition of January 1860, Darwin quoted Kingsley as "a celebrated cleric", and added the phrase "by the Creator" to the closing sentence, which from then on read "life, with its several powers, having been originally breathed by the Creator into a few forms or into one". While some commentators have taken this as a concession to religion that Darwin later regretted, Darwin's view at the time was of God creating life through the laws of nature, and even in the first edition there are several references to "creation".
What is the answer to this question: What were Darwin's views on the part of God in his theory?
****
So... Darwin's view at the time was of God creating life through the laws of nature

Here is a question about this article: Mali faces numerous health challenges related to poverty, malnutrition, and inadequate hygiene and sanitation. Mali's health and development indicators rank among the worst in the world. Life expectancy at birth is estimated to be 53.06 years in 2012. In 2000, 6265 percent of the population was estimated to have access to safe drinking water and only 69 percent to sanitation services of some kind. In 2001, the general government expenditures on health totalled about US$4 per capita at an average exchange rate.
What is the answer to this question: What four main health problems do the Malian people currently have?
****
So...
poverty, malnutrition, and inadequate hygiene and sanitation
