For the 2nd question,
A is correct because the first paragraph states that practices modern science condemns actually played a "critical role in historical moments of scientific progress" and that "scientists should think twice before they condemn them." The second paragraph details the Galileo case study as a major example of "crucial scientific advancement" achieved via "unscientific" practices (like circular reasoning and propaganda). This directly implies that because a core historical example of progress relied on these methods, science needs to expand and revise its definition of acceptable practice.
B is incorrect because the passage explicitly states Feyerabend highlights Galileo's work to "cast doubt on whether these 'unscientific' practices really deserve the criticism they so often garner," rather than to paint science as negatively controversial.
C is incorrect because while paragraph one mentions "subjective paths to truth," the passage never implies that modern science must actively adopt specific 17th-century methods to preserve subjectivity.
D is incorrect because the text notes that Galileo "essentially begged the question" (circular reasoning), but Feyerabend uses this detail to vindicate Galileo's broader methodology, not to establish a rigid rule for when tautologies are acceptable.
E is incorrect because it is a total opposite. Feyerabend uses a historical example to successfully back his philosophical claims, meaning he believes historical examples are valuable, not doomed to failure
