Answer:
1. Because she studied (a positive), but couldn't (a negative word), it means that you must use "but" or another word to describe it:
Lara studied several hours every night, but she couldn't earn higher than a B on the daily quizzes.
2. This is a run-on sentence, because it is best to separate both of them. However, if added together, there is need of a comma:
After Audie Murphy had proved himself a true hero in World War II, he became a hero of the silver screen in many actions films.
3. Again, this is a run-on sentence in which it would be best to separate both of the sentence fragments. However, since this is not an answer choice, it is best to separate using a comma:
The invention of the telescope led later astronomers to the discovery of countless celestial objects, yet it failed at the time to bring its inventor the recognition he was due.
4. He awoke from his nap while riding in the passenger seat of the car, Brian was surprised to discover that his father had driven several hundred miles.
"When he awoke from his nap" is a better choice, because while it describes the past, it should be put from a present-time view, which means that it must connect to the present-time from the past.

She is scared of holding it. If she was able to hold it without any fear, there would not be a problem.
Answer:The first sentence describes how Federigo lived happily after his marriage. However, I do not feel that Federigo is truly in love with his wife. The references to his “wealthy” wife and his better managed “financial affairs” give me the impression that Federigo lacks passion.
Rewritten sentence: He was married to the woman he loved, and she was also very rich. His situation motivated him to manage his money more wisely, and he had a happy life with her.
The second sentence tells the reader that Monna Giovanna “commended,” or praised, Federigo for the “greatness of his spirit” despite having “lost all hope of getting the falcon” and “improving the health of her son.” She also “reproached” (gently scolded) Federigo for killing the Falcon. These words show that Monna is a gentle and sensitive person, and yet she has a strong spirit. Many people in her situation would have lost control and shouted or wept in this situation. However, Monna praises and thanks Federigo for his “good will” and accepts her son’s fate.
Rewritten sentence: When she realized Federigo had killed the falcon, she gently scolded him. But secretly she thought that he had acted in an honorable manner, despite being poor. She thanked Federigo for his generosity to her. She was sad as she returned to her sick son because with the falcon dead, she had no hope of saving his life.
