1. Governments worldwide are working together to project the environment for pollution
    A. **worldwide**
          B. **are working**
            C. **to project**
              D. **for**

2. My uncle is one of the best environmentalist in my country
    A. **My**
                      B. **the best**

**Corrections:**
1. "for" should be corrected to "against" for the context of pollution: "to project the environment **against** pollution".
2. "environmentalist" should be corrected to "environmentalists" because it refers to plural ("one of the best environmentalists").
