Problem: Please answer a question about the following article about Middle Ages:
Monastic reform became an important issue during the 11th century, as elites began to worry that monks were not adhering to the rules binding them to a strictly religious life. Cluny Abbey, founded in the Mâcon region of France in 909, was established as part of the Cluniac Reforms, a larger movement of monastic reform in response to this fear.

In what century was thought given to monastic reform?

Defensive Counterair (DCA) is defined as "all the defensive measures designed to detect, identify, intercept, and destroy or negate enemy forces attempting to penetrate or attack through friendly airspace" (JP 1-02). A major goal of DCA operations, in concert with OCA operations, is to provide an area from which forces can operate, secure from air and missile threats. The DCA mission comprises both active and passive defense measures. Active defense is "the employment of limited offensive action and counterattacks to deny a contested area or position to the enemy" (JP 1-02). It includes both ballistic missile defense and air breathing threat defense, and encompasses point defense, area defense, and high value airborne asset defense. Passive defense is "measures taken to reduce the probability of and to minimize the effects of damage caused by hostile action without the intention of taking the initiative" (JP 1-02). It includes detection and warning; chemical, biological, radiological, and nuclear defense; camouflage, concealment, and deception; hardening; reconstitution; dispersion; redundancy; and mobility, counter-measures, and stealth.

What does the abbreviation DCA stand for?

Problem: During the Pacific War Funafuti was used as a base to prepare for the subsequent seaborn attacks on the Gilbert Islands (Kiribati) that were occupied by Japanese forces. The United States Marine Corps landed on Funafuti on 2 October 1942 and on Nanumea and Nukufetau in August 1943. The Japanese had already occupied Tarawa and other islands in what is now Kiribati, but were delayed by the losses at the Battle of the Coral Sea. The islanders assisted the American forces to build airfields on Funafuti, Nanumea and Nukufetau and to unload supplies from ships. On Funafuti the islanders shifted to the smaller islets so as to allow the American forces to build the airfield and to build naval bases and port facilities on Fongafale. A Naval Construction Battalion (Seabees) built a sea plane ramp on the lagoon side of Fongafale islet for seaplane operations by both short and long range seaplanes and a compacted coral runway was also constructed on Fongafale, with runways also constructed to create Nanumea Airfield and Nukufetau Airfield. USN Patrol Torpedo Boats (PTs) were based at Funafuti from 2 November 1942 to 11 May 1944.
On what islet did US forces build a seaplane ramp?
The answer is the following: Fongafale

Here is a question about this article: The Hortensian Law deprived the patricians of their last weapon against the plebeians, and thus resolved the last great political question of the era. No such important political changes occurred between 287 BC and 133 BC. The important laws of this era were still enacted by the senate. In effect, the plebeians were satisfied with the possession of power, but did not care to use it. The senate was supreme during this era because the era was dominated by questions of foreign and military policy. This was the most militarily active era of the Roman Republic.
What is the answer to this question: Why was the senate considered to be supreme during this time?
****
So...
because the era was dominated by questions of foreign and military policy
