Problem: Karl Popper:

Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolutionit is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype.

Popper's model of evolution is part of what family of models?

Problem: At the start of her reign Victoria was popular, but her reputation suffered in an 1839 court intrigue when one of her mother's ladies-in-waiting, Lady Flora Hastings, developed an abdominal growth that was widely rumoured to be an out-of-wedlock pregnancy by Sir John Conroy. Victoria believed the rumours. She hated Conroy, and despised "that odious Lady Flora", because she had conspired with Conroy and the Duchess of Kent in the Kensington System. At first, Lady Flora refused to submit to a naked medical examination, until in mid-February she eventually agreed, and was found to be a virgin. Conroy, the Hastings family and the opposition Tories organised a press campaign implicating the Queen in the spreading of false rumours about Lady Flora. When Lady Flora died in July, the post-mortem revealed a large tumour on her liver that had distended her abdomen. At public appearances, Victoria was hissed and jeered as "Mrs. Melbourne".
Who was rumored to be the mother of Flora Hastings "pregnancy"?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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?
A: Dowding
