Regarding sentence 9:

"The boy sitting at the front (of the group) is wearing a black tracksuit, a baseball cap with a red peak (or visor?), and a blue wind jacket with a zip-up pocket (?) at the front."

To check this sentence, you can focus on the clothing items mentioned and their descriptions. Look for keywords that will help you identify if the sentence is grammatically correct and makes sense in the context.

In this case, the sentence mentions specific clothing items such as a black tracksuit, a baseball cap with a red peak (or visor?), and a blue wind jacket with a zip-up pocket (?). To verify the sentence, you can research the descriptions of these clothing items or double-check with an official style guide.

Regarding sentence 10:

"They all look happy and eager to go on (?) OR to take part in the competition."

To check this sentence, you can analyze the context and meaning of the sentence. If the sentence is referring to a group of people who appear happy and eager, it is likely grammatically correct. However, if the intended meaning is not clear, you may need more context or additional information to determine the accuracy of the sentence.

Regarding sentence 11:

"If you go hiking, remember to take the following items with you: a compass, a map, comfortable hiking boots, a hooded wind jacket, an extra pair of tracksuit bottoms, a fleece, a pair of gloves (?), and knee sponge (?) socks."

To verify this sentence, you can cross-reference the list of items mentioned with a hiking or outdoor equipment checklist. Check for the proper spelling and accuracy of each item. If there are any terms you are unsure about, you can research their definitions or consult a well-known hiking guide for confirmation.

Regarding sentence 12:

"She has a red cap on and a hood over it. (??)"

To check this sentence, you can analyze the context and meaning. If the sentence is saying that "she" is wearing a red cap and has a hood covering it, it is grammatically correct. However, without additional context or information, it may be difficult to determine the accuracy of the sentence.

Regarding your question, "Can you say: she has a pair of earrings on?"

Based on the information you provided, there is no mention of earrings in any of the sentences you wanted to check. Therefore, without any context or indication, it would not be accurate to say that "she" has a pair of earrings on.
