The second main principle, sola fide (by faith alone), states that faith in Christ is sufficient alone for eternal salvation. Though argued from scripture, and hence logically consequent to sola scriptura, this is the guiding principle of the work of Luther and the later reformers. Because sola scriptura placed the Bible as the only source of teaching, sola fide epitomises the main thrust of the teaching the reformers wanted to get back to, namely the direct, close, personal connection between Christ and the believer, hence the reformers' contention that their work was Christocentric.
What was Luther's main principle?
sola fide (by faith alone)

Input: Multiracial American
After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.

What was it once considered socially advantageous to do?
Output: try to "pass" as white

Input: Article: Regarding the monastic rules, the Buddha constantly reminds his hearers that it is the spirit that counts. On the other hand, the rules themselves are designed to assure a satisfying life, and provide a perfect springboard for the higher attainments. Monastics are instructed by the Buddha to live as "islands unto themselves". In this sense, living life as the vinaya prescribes it is, as one scholar puts it: "more than merely a means to an end: it is very nearly the end in itself."

Now answer this question: Monastics are instructed by the Buddha to live as what?

Output: islands unto themselves

Here is a question about this article: All animals have eukaryotic cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules. During development, it forms a relatively flexible framework upon which cells can move about and be reorganized, making complex structures possible. In contrast, other multicellular organisms, like plants and fungi, have cells held in place by cell walls, and so develop by progressive growth. Also, unique to animal cells are the following intercellular junctions: tight junctions, gap junctions, and desmosomes.
What is the answer to this question: What is the extracellular matrix surrounding eukaryotic cells made of?
****
So... collagen and elastic glycoproteins

Article: There are 17 laws in the official Laws of the Game, each containing a collection of stipulation and guidelines. The same laws are designed to apply to all levels of football, although certain modifications for groups such as juniors, seniors, women and people with physical disabilities are permitted. The laws are often framed in broad terms, which allow flexibility in their application depending on the nature of the game. The Laws of the Game are published by FIFA, but are maintained by the International Football Association Board (IFAB). In addition to the seventeen laws, numerous IFAB decisions and other directives contribute to the regulation of football.

Question: Who maintains the Laws of the Game?
Ans:
International Football Association Board (IFAB)
