Problem: London's defences were rapidly reorganised by General Pile, the Commander-in-Chief of Anti-Aircraft Command. The difference this made to the effectiveness of air defences is questionable. The British were still one-third below the establishment of heavy anti-aircraft artillery AAA (or ack-ack) in May 1941, with only 2,631 weapons available. Dowding had to rely on night fighters. From 1940 to 1941, the most successful night-fighter was the Boulton Paul Defiant; its four squadrons shot down more enemy aircraft than any other type. AA defences improved by better use of radar and searchlights. Over several months, the 20,000 shells spent per raider shot down in September 1940, was reduced to 4,087 in January 1941 and to 2,963 shells in February 1941.
Who relied on night fighters?
The answer is the following: Dowding

Problem: As a Southern Gothic novel and a Bildungsroman, the primary themes of To Kill a Mockingbird involve racial injustice and the destruction of innocence. Scholars have noted that Lee also addresses issues of class, courage, compassion, and gender roles in the American Deep South. The book is widely taught in schools in the United States with lessons that emphasize tolerance and decry prejudice. Despite its themes, To Kill a Mockingbird has been subject to campaigns for removal from public classrooms, often challenged for its use of racial epithets.
What has caused the use of the novel in classrooms to be challenged?
The answer is the following: racial epithets

Problem: In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President.
What type of agreement requires majority approval by both the House and the Senate before or after a treaty is signed by the United States president?
The answer is the following:
congressional-executive agreements
