Namely, most human language feature four skills, divided into productive skills and receptive skills.
- Productive skills: speaking and writing.
- Receptive skills: listening and reading.
For a long time, human languages only featured one productive skill, speaking, and one receptive skill, listening. Writing and reading would appear at a later time within the ancient cultures of Mesopotamia (who invented the cuneiform writing system) and ancient Egypt (who developed hieroglyphic and demotic writing systems). Even today, many human groups living in isolated and remote areas have not developed writing and reading, relying solely on speaking and listening and on oral tradition (passing down the history of the group from one generation to the next) for their communication needs.
Answer:
1. The highest temperature in microwave for reheating depends on the manufacturers, but a study shows that it can reach up to 191oC for reheating and up to 200oC for cooking [4]. Microwave-safe plastics are those being able to withstand without smelting.
2. Microwaving food in plastic can cause chemicals to leach to food. Migration is likely to be greater with fatty food such as cheese and meat.
3. The best types of plastic for kitchen are those don't contain phthalates (polyvinyle chloride) and bisphenol A (polycarbonate). By contrast, the worst contain one of the two.[1][2][3]
Explanation:
Phthalates and bisphenol A are endocrine disrupters, both are known as reproductive toxicants. So if you use plastic in microwave, choose the ones with microwave-safe label. It's because they must pass a strict safety test by FDA to come to the market.[1][2]

The reason that Thomas Paine brings up the opposing argument that the colonies have been well protected by the British is:
B. To create a chance to prove his opponents wrong
Thomas Paine states in “The American Crisis, No.1" about the importance of Independence for the people of America. He approaches every people through emotional thoughts and ideas. His writings persuade people to think over the need for Independence of themselves and for their children. Thomas Paine didn’t agree with the fact that Great Britain has always benefited the colonies and will ever benefit them in the future. He opposes the fact that it will provide security and protection to the colonized countries.
