Here is a question about this article: Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as BoseEinstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quarkgluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470380 BC).
What is the answer to this question: People have been wondering about the nature of matter for the entire history of what branch of science?

So... natural sciences

Here is a question about this article: Some of Jackson's successors made no use of the veto power, while others used it intermittently. It was only after the Civil War that presidents began to use the power to truly counterbalance Congress. Andrew Johnson, a Democrat, vetoed several Reconstruction bills passed by the "Radical Republicans." Congress, however, managed to override fifteen of Johnson's twenty-nine vetoes. Furthermore, it attempted to curb the power of the presidency by passing the Tenure of Office Act. The Act required Senate approval for the dismissal of senior Cabinet officials. When Johnson deliberately violated the Act, which he felt was unconstitutional (Supreme Court decisions later vindicated such a position), the House of Representatives impeached him; he was acquitted in the Senate by one vote.
What is the answer to this question: What act did congress pass that gave the senate the right to approve the dismissal of a cabinet official?

So... Tenure of Office Act

Here is a question about this article: Bowers and Tanselle argue for rejecting textual variants that an author inserted at the suggestion of others. Bowers said that his edition of Stephen Crane's first novel, Maggie, presented "the author's final and uninfluenced artistic intentions." In his writings, Tanselle refers to "unconstrained authorial intention" or "an author's uninfluenced intentions." This marks a departure from Greg, who had merely suggested that the editor inquire whether a later reading "is one that the author can reasonably be supposed to have substituted for the former", not implying any further inquiry as to why the author had made the change.
What is the answer to this question: What idea did Tanselle champion?

So...
unconstrained authorial intention
