Congress often enacts statutes that grant broad rulemaking authority to federal agencies. Often, Congress is simply too gridlocked to draft detailed statutes that explain how the agency should react to every possible situation, or Congress believes the agency's technical specialists are best equipped to deal with particular fact situations as they arise. Therefore, federal agencies are authorized to promulgate regulations. Under the principle of Chevron deference, regulations normally carry the force of law as long as they are based on a reasonable interpretation of the relevant statutes.
The Chevron deference prevents regulations from interpreting what?
A: unanswerable

Victoria later described her childhood as "rather melancholy". Her mother was extremely protective, and Victoria was raised largely isolated from other children under the so-called "Kensington System", an elaborate set of rules and protocols devised by the Duchess and her ambitious and domineering comptroller, Sir John Conroy, who was rumoured to be the Duchess's lover. The system prevented the princess from meeting people whom her mother and Conroy deemed undesirable (including most of her father's family), and was designed to render her weak and dependent upon them. The Duchess avoided the court because she was scandalised by the presence of King William's bastard children, and perhaps prompted the emergence of Victorian morality by insisting that her daughter avoid any appearance of sexual impropriety. Victoria shared a bedroom with her mother every night, studied with private tutors to a regular timetable, and spent her play-hours with her dolls and her King Charles spaniel, Dash. Her lessons included French, German, Italian, and Latin, but she spoke only English at home.
Who was extremely protective over Victoria?
A: mother

In 1840, Louis Philippe I obtained permission from the British to return Napoleon's remains to France. On 15 December 1840, a state funeral was held. The hearse proceeded from the Arc de Triomphe down the Champs-Élysées, across the Place de la Concorde to the Esplanade des Invalides and then to the cupola in St Jérôme's Chapel, where it remained until the tomb designed by Louis Visconti was completed. In 1861, Napoleon's remains were entombed in a porphyry sarcophagus in the crypt under the dome at Les Invalides.
In what year was Napoleon's final tomb completed?

The dismal results caused Gephardt to drop out and later endorse Kerry. Carol Moseley Braun also dropped out, endorsing Howard Dean. Besides the impact of coming in third, Dean was further hurt by a speech he gave at a post-caucus rally. Dean was shouting over the cheers of his enthusiastic audience, but the crowd noise was being filtered out by his unidirectional microphone, leaving only his full-throated exhortations audible to the television viewers. To those at home, he seemed to raise his voice out of sheer emotion. The incessant replaying of the "Dean Scream" by the press became a debate on the topic of whether Dean was the victim of media bias. The scream scene was shown approximately 633 times by cable and broadcast news networks in just four days following the incident, a number that does not include talk shows and local news broadcasts. However, those who were in the actual audience that day insist that they were not aware of the infamous "scream" until they returned to their hotel rooms and saw it on TV.
Which candidate, after dropping out, went on to endorse Kerry?
A:
Gephardt
