70. Passage for Q70-72: The history of scientific discovery is replete with instances where groundbreaking theories were initially met with resistance from the established scientific community. This skepticism, while sometimes hindering progress, also serves as a crucial safeguard, preventing the premature acceptance of unverified claims. The process of rigorous peer review and empirical validation, though slow and arduous, ensures that only robust and reproducible findings ultimately contribute to the scientific canon. It is through this dialectical process of challenge and verification that scientific knowledge truly advances, rather than through unchallenged consensus. The passage implies that skepticism within the scientific community is:

Always detrimental to progress.
A necessary component of scientific advancement.
A rare occurrence.
Indicative of intellectual stagnation.

71. According to the author, the slow and arduous process of peer review is important because it:

Discourages new theories.
Ensures the rigor and reproducibility of findings.
Promotes unchallenged consensus.
Accelerates the acceptance of all claims.
