Final answer:
The passage does not specify the number of surgeries Dr. Edward plans to perform, but it implies that she performs a very high volume of surgeries under war conditions.
Step-by-step explanation:
The passage does not provide a specific number of surgeries that Dr. Edward plans to perform in less than ten days. However, it gives us an insight into the intense and difficult conditions under which she works. It describes how Dr. Edward continues to operate for extended periods, sometimes up to 60 hours without breaks for sleep, enduring the harsh conditions of shells and bombs falling on the hospital. This suggests a very high volume of surgical activity in a war-torn setting.
