Answer 1

1. She can have three problems-

Problem one- she is unable to focus and get a clear image. So, in this case she can first use the lower objective lens to find the specimen then she can use high power objective lens to focus on the object.

Problem 2- she is unable to see the inner structures of the object. She can use fine focus first and if she is still having a problem she can try oil immersion.

Problem 3- She is not able to get the object under the objective lens. For this she can use stage controls.
