11 Now that the tests have been done we know the origin of the disease.

Answer 2

Sure, I'll help you with the correct tense forms for the sentences:

10. The doctor wanted to know how long had passed since I last took that medicine.

11. Now that the tests have been done, we know the origin of the disease.

Explanation:

• In sentence 10, we use the past perfect tense "had passed" because the action of taking the medicine occurred before the doctor wanted to know about it.
• In sentence 11, we use the present perfect tense "have been done" to indicate that the tests were completed in the past and their results are relevant in the present moment. Also, we use the simple past tense "knew" in the second part of the sentence, as it's an event that followed the completion of the tests.
