Answer: The correct answer is:
• B) obstacle
Explanation: The sentence would read: "Like worked hard to overcome every obstacle placed in his path."
• Here's an explanation of why the other options are incorrect:
• A) diligence: Diligence refers to careful and persistent work or effort. While it is related to overcoming challenges, it doesn't directly fit the context of something that is "placed in his path." Diligence is more about the effort someone puts into their work rather than something that blocks their progress.
• C) arduous: Arduous means difficult, requiring a lot of effort and hard work. However, it doesn't specifically refer to something that is placed as an obstacle in someone's path. It's more about the overall difficulty of the task or journey.
• D) persistence: Persistence is the quality of continuing to do something even in the face of difficulties or obstacles. While it's related to overcoming challenges, it doesn't directly address the concept of something being placed in someone's path as an obstacle.
• In the given sentence, the word "overcome" suggests dealing with something that is in the way, which aligns best with the word "obstacle."
