Read the passage: "Universal school meal programs guarantee every student a free breakfast and lunch, regardless of household income. The approach defined the federal standard until the 1980s, when eligibility restrictions narrowed the program. Several districts have since piloted universal models again, and the results invite comparison. Portland's pilot raised participation from 61 percent to 89 percent, whereas participation in the neighboring control districts stayed flat. Similarly, attendance improved in the pilot schools, while disciplinary referrals for afternoon incidents fell by a fifth. Proponents argue the effects are causal: because hungry students struggle to concentrate, guaranteed meals remove a barrier that previously suppressed performance. Critics answer that the pilots coincided with a new attendance campaign, so the gains may not stem from meals at all. Evaluating both claims, this analysis finds the mechanism evidence persuasive and recommends phased adoption, with full rollout after two more years of tracking. The recommendation rests on the causal finding, not on the raw participation numbers, which both sides agree were large. The analysis therefore spends its final section rebutting the coincidence objection directly, showing that attendance gains appeared only in pilot schools and only after meals began, not during the campaign's early months." Which pattern dominates the organization of this passage?

Read the passage: "The collapse of the North Atlantic cod fishery in 1992 was not a single event but the end of a chain that built over two decades. Because factory trawlers adopted sonar in the 1970s, fleets could locate and harvest entire schools at once, and fishing pressure rose sharply. As a result, the spawning stock shrank to a fraction of its former size. Since older, larger fish produce far more eggs than young fish, the loss of the big breeders cut recruitment, the entry of new fish into the population. Consequently, even reduced harvests failed to let the stock rebuild, and therefore the government closed the fishery entirely. Ongoing warming of the region's waters, a contributing factor rather than the primary cause, has since slowed every recovery attempt. The moratorium put thirty thousand fishers out of work within three years, and the stock, once measured in millions of tons, has yet to recover to even a tenth of its former biomass three decades later. Economists tracing the regional downturn have followed the same chain backward, treating the collapse of the stock as the trigger for every later shock to the coastal economy." Which sequence correctly states the cause-effect chain described in the passage?

Read the passage: "Two protocols dominate telehealth triage. Protocol A routes patients through a scripted questionnaire before any clinician contact; Protocol B connects patients to a nurse within five minutes and screens afterward. Whereas Protocol A scales cheaply and handles routine cases well, Protocol B costs more per visit but catches urgent cases earlier. In contrast to both, a hybrid model, scripted screening with immediate nurse escalation for flagged symptoms, matches Protocol A's cost on routine volume while approaching Protocol B's detection rate on urgent cases. Similarly, a 2021 pilot and a 2023 replication both found the hybrid model missed only 2 percent of urgent presentations, compared with 9 percent under Protocol A and 3 percent under Protocol B. The authors position the hybrid model as the new standard, arguing that the older protocols each solved half the problem. The studies applied identical criteria, cost per visit, detection rate, and missed urgent cases, to all three models, which is what makes the recommendation a product of the comparison rather than of advocacy. The authors close by noting that any future protocol should be scored on the same three criteria, so the framework itself can be reused as the field changes." What function does the comparison serve in this research summary?
