SS4 was ground-breaking in the sense that it combined the advantages of part time and full-time four-wheel drive with four available options: 2H ( high-range rear-wheel drive ), 4H ( high-range full time four-wheel drive ), 4HLc ( high-range four-wheel drive with locked center differential ) and 4LLc ( low-range four-wheel drive with locked center differential ).

Gypsisols in the FAO World Reference Base for Soil Resources are soils with substantial secondary accumulation of gypsum ( CaSO < sub > 4 </ sub >. 2H < sub > 2 </ sub > O ).

Arsenate minerals usually refer to the naturally occurring orthoarsenates, possessing the ( AsO < sub > 4 </ sub >)< sup > 3 -</ sup > anion group and, more rarely, other arsenates with anions like AsO < sub > 3 </ sub >( OH )< sup > 2 -</ sup > ( also written HAsO < sub > 4 </ sub >< sup > 2 -</ sup >) ( example: pharmacolite Ca ( AsO < sub > 3 </ sub > OH )< sup >.</ sup > 2H < sub > 2 </ sub > O ) or ( very rarely ) < sup >-</ sup > ( example: andyrobertsite ).

Most anthodites are made of the mineral aragonite ( a variety of calcium carbonate, CaCO < sub > 3 </ sub >), although some are composed of gypsum ( CaSO < sub > 4 </ sub >· 2H < sub > 2 </ sub > O ).

The battle between William Howard Taft | Taft and Roosevelt bitterly split the Republican Party ; Taft's people dominated the party until 1936.

Of Taft's appointment, Roosevelt said, " If only there were three of you ; I could appoint one of you to the Court, one to the War Department and one to the Philippines.

Taft's spouse was determined to gain the White House and pressured him not to accept a court appointment ; other family members also strongly favored the Presidency for him.

The resulting tariff rates in the Payne – Aldrich Tariff Act of 1909 were too high for the progressives, based in part on Taft's campaign promises ; but instead of blaming the act's shortcomings on Senator Nelson W. Aldrich and big business, Taft claimed the responsibility, calling it the best bill to come from the Republican Party.

Taft's administration got a political boost after 25 western railroads announced an intent to raise rates by 20 %, and Taft responded, first with a threat to enforce the Sherman Antitrust Act against them ; he then negotiated a settlement whereby they agreed to submit delayed rate requests to a new Interstate Commerce Commission having authority over rate requests.

The President reviewed the matter, then fired Glavis and Pinchot ; Ballinger also tendered his resignation, which would have further served to end the matter were it not for Taft's refusal to accept it.

When the Republicans in 1964 gave Senator Barry Goldwater of Arizona, Taft's successor as the conservative leader, their presidential nomination, Dewey declined to even attend the GOP Convention in San Francisco ; it was the first Republican Convention he had missed since 1936.

In 1948 and 1952 Reece was a leading supporter of Taft's candidacy for the Republican presidential nomination ; however, Taft lost the nomination both times to moderate Republicans from New York.

Yet balanced against these achievements were: Taft's acceptance of a tariff with protective schedules that outraged progressive opinion ; his opposition to the entry of the state of Arizona into the Union because of its progressive constitution ; and his growing reliance on the conservative wing of his party.

Clark's Speakership was notable for two things: First, Clark's skill from 1910 to 1914 in maintaining party unity to block William Howard Taft's legislation and then pass Wilson's ; and second, Clark's splitting of the party in 1917 and 1918 when he opposed Wilson's decision to bring the United States into World War I.

He assesses the New Testament as " uninspired, but truthful ; sincere, able, vigorous, but fallible.

; however, a case of writer's block resulted in reportedly uninspired collaborations.

American Motors ' executives saw an opportunity to replace the " uninspired " Matador two-door hardtop with a new design to capture people looking for exciting, sporty styling in a market segment that was outpacing the rest of the automobile market ; and were looking to answer the demand for plush mid-size coupes after the end of the muscle car era.

After Stevens left the series, the team faltered ; the last five Wheeler & Woolsey pictures ( 1935 – 37 ) were weakened by the combination of bad scripts, lower budgets, and uninspired direction by lesser talents.

Punk was a kind of rebellious rock music that began in the 1970s, as a reaction against the popular music of the day, especially disco, which was seen as insipid and uninspired ; punk drew on American bands including the Velvet Underground, The Stooges and the New York Dolls.

Its primary advantage is that it is a moral choice ; ;

The greater the range of freedom for individual men, the greater the range of choice ; ;

They had been kind to us and we were indebted to them for one or two pleasant dinners, and for information as to where to shop, which dentist, doctor, plumber, and sitter to call ( not that there was much of a choice, since Catatonia was just a village ; ;

The choice of P and N determines the binomial distribution uniquely, and different choices always produce different distributions ( except when Af ; ;

In early childhood the choice of a companion is likely to be for another child of his own age or a year or two older, who can do the things he likes to do ; ;

The choice is yours: the revellings and banquetings of this world or quiet communion with God ; ;

In many cases such a selection can be made without invoking the axiom of choice ; this is in particular the case if the number of bins is finite, or if a selection rule is available: a distinguishing property that happens to hold for exactly one object in each bin.

The axiom of choice asserts the existence of such elements ; it is therefore equivalent to:

In the even simpler case of a collection of one set, a choice function just corresponds to an element, so this instance of the axiom of choice says that every nonempty set has an element ; this holds trivially.

" The problem then becomes that of constructing a well-ordering, which turns out to require the axiom of choice for its existence ; every set can be well-ordered if and only if the axiom of choice holds.

It is possible to prove many theorems using neither the axiom of choice nor its negation ; such statements will be true in any model of Zermelo – Fraenkel set theory ( ZF ), regardless of the truth or falsity of the axiom of choice in that particular model.

The members were given a choice of either offering armed forces or paying a tax to the joint treasury ; most states chose the tax.

In choosing analgesics, the severity and response to other medication determines the choice of agent ; the WHO pain ladder, originally developed in cancer-related pain, is widely applied to find suitable drugs in a stepwise manner.

Since the English Reformation, the Church of England has been more explicitly a state church and the choice is legally that of the British crown ; today it is made in the name of the Sovereign by the Prime Minister, from a shortlist of two selected by an ad hoc committee called the Crown Nominations Commission.

A pitcher is only charged with the number of runners that reached base while he was pitching, and this does not include baserunners who reach base as the result of a fielder's choice play that removes an existing runner ; such a runner is charged to the pitcher whose baserunner has been removed by the fielder's choice play.
