Consider the following text to answer the question.
Global temperatures in 2025 were slightly lower than in 2024 because of La Niña, a natural weather pattern that cools the Pacific Ocean.
Even so, 2025 became the third warmest year ever recorded. The last three years were the hottest in history, which shows a clear long-term warming trend. Scientists say today’s temperatures stay far above levels from before the heavy use of fossil fuels.
Experts explain that this warming happens mainly because people continue to release carbon emissions. Although some cooling came from natural causes, it didn’t stop the overall rise. Scientists warn that more heat records and stronger weather events will follow if emissions don’t fall quickly. Fires, floods, and heat waves have already affected many parts of the world.
Researchers say the science is very clear and not uncertain. Governments, companies, and individuals all play a role. People can vote, spend money carefully, and support cleaner energy. Reducing emissions soon can help slow warming and protect the planet.
Based on the causal reasoning and argumentative progression developed in the text, the cooling observed in 2025 is best characterized as:

Consider the following text to answer the question.
Ivory Coast plans to buy the entire volume of cocoa that farmer groups cannot sell. The government wants to make sure farmers still receive money even though cocoa prices fall to the lowest level in two years.
Cocoa plays a very important role in the country because it makes up a large part of the economy and supports many families.
Exports slow down after chocolate makers use less cocoa when prices rise before. This situation causes large cocoa stocks to build up. The government now steps in and works with trusted local companies and international buyers to collect and buy the cocoa. Officials say this plan should protect farmers and keep the market stable.
Ivory Coast produces more cocoa than any other country in the world. About one out of five people depends on this work for their income. With prices down by about five dollars per kilo, many farmers face problems. The government hopes this action will support producers and prevent serious economic damage.
In the sentence “The government now steps in and works with trusted local companies and international buyers”, the expression “steps in”, as used in context, most plausibly conveys the idea that the government:
