Problem: Dwight D. Eisenhower:

Operation Torch also served as a valuable training ground for Eisenhower's combat command skills; during the initial phase of Generalfeldmarschall Erwin Rommel's move into the Kasserine Pass, Eisenhower created some confusion in the ranks by some interference with the execution of battle plans by his subordinates. He also was initially indecisive in his removal of Lloyd Fredendall, commanding U.S. II Corps. He became more adroit in such matters in later campaigns. In February 1943, his authority was extended as commander of AFHQ across the Mediterranean basin to include the British Eighth Army, commanded by General Sir Bernard Montgomery. The Eighth Army had advanced across the Western Desert from the east and was ready for the start of the Tunisia Campaign. Eisenhower gained his fourth star and gave up command of ETOUSA to become commander of NATOUSA.

Who commanded II Corps before being removed by Eisenhower?

A: Lloyd Fredendall

Problem: The lower (Triassic) boundary is set by the PermianTriassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the CretaceousTertiary (KT) extinction event (now more accurately called the CretaceousPaleogene (or KPg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatan Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the CretaceousPaleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.
What is the possible cause of the upper Cretaceous extinction event ?

Answer: KPg) extinction

Context and question: Although provision is made in Title 10 of the United States Code for the Secretary of the Air Force to appoint warrant officers, the Air Force does not currently use warrant officer grades, and is the only one of the U.S. Armed Services not to do so. The Air Force inherited warrant officer ranks from the Army at its inception in 1947, but their place in the Air Force structure was never made clear.[citation needed] When the Congress authorized the creation of two new senior enlisted ranks in 1958, Air Force officials privately concluded that these two new "super grades" could fill all Air Force needs then performed at the warrant officer level, although this was not publicly acknowledged until years later.[citation needed] The Air Force stopped appointing warrant officers in 1959, the same year the first promotions were made to the new top enlisted grade, Chief Master Sergeant. Most of the existing Air Force warrant officers entered the commissioned officer ranks during the 1960s, but small numbers continued to exist in the warrant officer grades for the next 21 years.
When did Congress authorize the creation of two new senior officer grades?
Answer: 1958
