Problem: Karl Popper:

Karl Popper's rejection of Marxism during his teenage years left a profound mark on his thought. He had at one point joined a socialist association, and for a few months in 1919 considered himself a communist. During this time he became familiar with the Marxist view of economics, class-war, and history. Although he quickly became disillusioned with the views expounded by Marxism, his flirtation with the ideology led him to distance himself from those who believed that spilling blood for the sake of a revolution was necessary. He came to realise that when it came to sacrificing human lives, one was to think and act with extreme prudence.

What ideology did Popper never become disillusioned with?

Context and question: In an interrogative main clause the usual word order is: conjugated verb followed by subject; other verbs in final position: "Kun jij je pen niet vinden?" (literally "Can you your pen not find?") "Can't you find your pen?"
In the Dutch equivalent of a wh-question the word order is: interrogative pronoun (or expression) + conjugated verb + subject; other verbs in final position: "Waarom kun jij je pen niet vinden?" ("Why can you your pen not find?") "Why can't you find your pen?""
In a tag question the word order is the same as in a declarative clause: "Jij kunt je pen niet vinden?" ("You can your pen not find?") "You can't find your pen?""
A subordinate clause does not change its word order: "Kun jij je pen niet vinden omdat het veel te donker is?" ("Can you your pen not find because it far too dark is?") "Can you not find your pen because it's too dark?""
What's the English type equivalent for the Dutch word order that is an interrogative pronoun/expression, then a verb followed by a subject?
Answer: a wh-question

Question: Patent infringement typically is caused by using or selling a patented invention without permission from the patent holder. The scope of the patented invention or the extent of protection is defined in the claims of the granted patent. There is safe harbor in many jurisdictions to use a patented invention for research. This safe harbor does not exist in the US unless the research is done for purely philosophical purposes, or in order to gather data in order to prepare an application for regulatory approval of a drug. In general, patent infringement cases are handled under civil law (e.g., in the United States) but several jurisdictions incorporate infringement in criminal law also (for example, Argentina, China, France, Japan, Russia, South Korea).
Is there an answer to this question: What types of cases in Russia and China are handled by civil law?
