A United States presidential nominating convention is a political convention held every four years in the United States by most of the political parties who will be fielding nominees in the upcoming U.S. presidential election. The formal purpose of such a convention is to select the party's nominee for popular election as President, as well as to adopt a statement of party principles and goals known as the party platform and adopt the rules for the party's activities, including the presidential nominating process for the next election cycle.

Calendars

The convention cycle begins with the Call to Convention. Usually issued about 18 months in advance, the Call is an invitation from the national party to the state and territory parties to convene to select a presidential nominee. It also sets out the number of delegates to be awarded to each, as well as the rules for the nomination process. The conventions are usually scheduled for four days of business, with the exception of the 1972 Republican and 2012 Democratic conventions, which were three days each. (The 2008 and 2012 Republican conventions were also three days each, but in each case was shortened from the scheduled four days due to weather issues.)

There is no statute dictating the order of the conventions, but since 1956 the party to which the incumbent president belongs has held its convention second. Between 1864 and 1952, the Democrats went second every year (except for 1888). In 1956, when Republican Dwight D. Eisenhower was the incumbent, the Democrats went first, and the party out of power has gone first ever since. (Between 1936 and 1952, during administrations led by Democratic presidents Franklin D. Roosevelt and Harry S. Truman, the Democrats had their convention after the Republicans, but it is unclear whether they went second because they held the White House or because they had almost always gone second.) Since 1952, all major party conventions have been held in the months of July, August or (for the first time in 2004), early September. (Election laws in some states would likely prevent conventions from moving into mid-September.) Between the middle of the 20th century and 2004, the two major party conventions were primarily scheduled about one month apart, often with the Summer Olympics in between so they did not have to compete for viewers. In 1996, both were held in August to accommodate the Atlanta Olympics in July, the last Summer Olympics to date to be played in the U.S. In 2000, both conventions preceded the Sydney Olympics in late September.

In 2016, both the Republican and Democratic conventions moved to July, before the Rio de Janeiro Olympics in August. One reason why the Republican Party wanted a July convention was to help avoid a drawn-out primary bat-tle similar to what happened in 2012 that left the party fractured heading into the general election. The Democrats then followed suit so they could provide a quicker response to the Republicans, rather than wait for more than two weeks until after the Olympics are over.

Can i have brainliest please and i would be happy to help you again bye luv <3

the 2nd option is the answer

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
