Sra

1) The first sentence is mostly correct. However, it should be clarified that the average amount of pocket money is £8 for boys specifically, and they spend it on items such as sweets, fast food, CDs, and computer games.

2) The second sentence is incorrect. Colorado is not a country; it is a state in the United States of America. Therefore, the sentence should be revised to say, "Jess comes from Colorado, which is a state in the south-west of the USA."

3) The third sentence is correct. It states that Colorado is larger in size than Britain, but its population is smaller.

4) The fourth sentence is correct. It describes two tourist attractions in Colorado: the Rocky Mountain National Park and the Mesa Verde National Park. The sentence also provides details about the Rocky Mountain National Park, mentioning its magnificent scenery and fascinating animals.

5) The fifth sentence is correct. It explains that the Mesa Verde National Park is unique because it features cliff caves dating back to the 6th century.

6) The sixth sentence contains a mistake. The biggest rainforest in the world is not in Brazil, but rather in the Amazon region, which includes several South American countries such as Brazil. The sentence should be revised to say, "South America is home to the largest rainforest in the world, which is located in Brazil, among other countries. Additionally, South America is home to the world's driest desert, the Atacama Desert."

7) The seventh sentence is correct. It states that the Andes mountain range is the longest in the world and stretches from the south of Chile to Venezuela.

8) The eighth sentence is correct. It indicates that in South America, there are about half of the world's animals and insects.

9) The ninth sentence is incomplete. We need more information about the unique aspect of the school week at Ravenscourt School in London for proper evaluation or revision.
