1. What English-speaking countries do you know? 2. Is English or French the most important international language nowadays? 3. What foreign languages are popular in Russia? 4. Do you know American equivalents for the British words "biscuits," "sweets," "autumn"?

Some of the English-speaking countries I know include the United States, Canada, the United Kingdom, Australia, New Zealand, Ireland, and South Africa. These countries primarily use English as their main language.

While both English and French are important international languages, English is generally considered the most important today. It is the dominant language in global business, science, technology, and entertainment, and it is widely spoken as a second language around the world.

In Russia, the most popular foreign languages are English, German, and French. English is especially in demand, as it is often taught in schools and universities and is important for international business and travel. German and French are also commonly learned, especially by those interested in cultural and historical connections with Germany and France.

In American English, the British word "biscuits" is equivalent to "cookies." The British word "sweets" is called "candy" in the U.S. And instead of "autumn," Americans typically say "fall."
