Answer:
The author mostly focuses on George Washington's experiences studying to become and working as a surveyor. It discusses how he learned to survey land using regular field books. This was an important skill for him as he pursued a career in surveying the Virginia territory.
Step-by-step explanation:
The secondhand account is mainly focusing on how George Washington learned to survey land using regular field books. A secondhand account means that the information is not directly from George Washington himself, but rather from someone else who heard or read about it.
In this case, the author is discussing George Washington's experiences and methods as a surveyor. Surveying is the process of measuring and mapping out the land. Regular field books were commonly used by surveyors to record their measurements, notes, and calculations while surveying.
By focusing on George Washington's learning process and the use of field books, the author highlights the practical aspects of his profession. This information helps the reader understand the tools and techniques that George Washington employed in his work as a surveyor.
The other options mentioned in the question (A, C, and D) are not the primary focus of the secondhand account. Option A, George Washington's experience trying to get some sleep after a day of surveying, may be mentioned in passing but is not the main focus. Option C, George Washington's belief that time was too precious to lose, and option D, his experiences studying to become and working as a surveyor, are not the central topics discussed in the secondhand account.
