Here is a question about this article: Popper held that rationality is not restricted to the realm of empirical or scientific theories, but that it is merely a special case of the general method of criticism, the method of finding and eliminating contradictions in knowledge without ad-hoc-measures. According to this view, rational discussion about metaphysical ideas, about moral values and even about purposes is possible. Popper's student W.W. Bartley III tried to radicalise this idea and made the controversial claim that not only can criticism go beyond empirical knowledge, but that everything can be rationally criticised.
What is the answer to this question: Which of Popper's students argued that rational criticism should be most widely applied?
****
So... W.W. Bartley III

Here is a question about this article: Only 14% of the population speaks Portuguese, established as the official language in the colonial period. Almost half the population (44%) speaks Crioulo, a Portuguese-based creole language, and the remainder speak a variety of native African languages. The main religions are African traditional religions and Islam; there is a Christian (mostly Roman Catholic) minority. The country's per-capita gross domestic product is one of the lowest in the world.
What is the answer to this question: What are the two main religions?
****
So... African traditional religions and Islam

Here is a question about this article: The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.
What is the answer to this question: What is the first purpose of air defence?
****
So...
detect hostile aircraft
