At the official counting of the electoral votes on January 6, a motion was made contesting Ohio's electoral votes. Because the motion was supported by at least one member of both the House of Representatives and the Senate, election law mandated that each house retire to debate and vote on the motion. In the House of Representatives, the motion was supported by 31 Democrats. It was opposed by 178 Republicans, 88 Democrats and one independent. Not voting were 52 Republicans and 80 Democrats. Four people elected to the House had not yet taken office, and one seat was vacant. In the Senate, it was supported only by its maker, Senator Boxer, with 74 Senators opposed and 25 not voting. During the debate, no Senator argued that the outcome of the election should be changed by either court challenge or revote. Senator Boxer claimed that she had made the motion not to challenge the outcome, but to "shed the light of truth on these irregularities."

What was the decision regarding the motion to re-count the votes, after each House finalized their debates?
Answer: During the debate, no Senator argued that the outcome of the election should be changed by either court challenge or revote

Problem: The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,57549,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.
What was the total worldwide energy consumption in 2012?
The answer is the following: 559.8 EJ

The first Industrial Revolution merged into the Second Industrial Revolution around 1850, when technological and economic progress gained momentum with the development of steam-powered ships and railways, and later in the 19th century with the internal combustion engine and electric power generation. The Second Industrial Revolution was a phase of the Industrial Revolution; labeled as the separate Technical Revolution. From a technological and a social point of view there is no clean break between the two. Major innovations during the period occurred in the chemical, electrical, petroleum, and steel industries. Specific advancements included the introduction of oil fired steam turbine and internal combustion driven steel ships, the development of the airplane, the practical commercialization of the automobile, mass production of consumer goods, the perfection of canning, mechanical refrigeration and other food preservation techniques, and the invention of the telephone.
When did the first industrial revolution merge into the second?
around 1850

Here is a question about this article: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
What is the answer to this question: Why is it important to document variations in witness texts when compiling a critical text?
****
So...
so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition.
