A period is a horizontal row in the periodic table. Although groups generally have more significant periodic trends, there are regions where horizontal trends are more significant than vertical group trends, such as the f-block, where the lanthanides and actinides form two substantial horizontal series of elements.

Based on this passage, this is a horizontal arrangement of elements in the periodic table?

Stream of random thoughts: To answer the question, consider the following: A period is a horizontal row in the periodic table.... The answer is A period.

He next experimented with a high-pressure hydrogen jet by which low temperatures were realised through the Joule -- Thomson effect, and the successful results he obtained led him to build at the Royal Institution a large regenerative cooling refrigerating machine. Using this machine in 1898, liquid hydrogen was collected for the first time, solid hydrogen following in 1899. He tried to liquefy the last remaining gas, helium, which condenses into a liquid at 268.9 C, but owing to a number of factors, including a short supply of helium, Dewar was preceded by Heike Kamerlingh Onnes as the first person to produce liquid helium, in 1908. Onnes would later be awarded the Nobel Prize in Physics for his research into the properties of matter at low temperatures -- Dewar was nominated several times, but never succeeded in winning the Nobel Prize.

Passage: Titanic was under the command of Edward Smith, who also went down with the ship. The ocean liner carried some of the wealthiest people in the world, as well as hundreds of emigrants from Great Britain and Ireland, Scandinavia and elsewhere throughout Europe who were seeking a new life in the United States. The first-class accommodation was designed to be the pinnacle of comfort and luxury, with an on-board gymnasium, swimming pool, libraries, high-class restaurants and opulent cabins. A high-powered radiotelegraph transmitter was available for sending passenger "marconigrams" and for the ship's operational use. Although Titanic had advanced safety features such as watertight compartments and remotely activated watertight doors, there were not enough lifeboats to accommodate all of those aboard, due to outdated maritime safety regulations. Titanic only carried enough lifeboats for 1,178 people -- slightly more than half of the number on board, and one third of her total capacity.

Question: Based on this passage, who was sailing the titanic when it crashed?
Stream of random thoughts: This is the relevant information: Titanic was under the command of Edward Smith, who also went down with the ship.... The answer is Edward Smith.
