Final answer:
Smooth sailing means easy progress or a smooth journey without any obstacles or difficulties. It describes a situation or task that is going smoothly and without any problems.
Step-by-step explanation:
Smooth sailing refers to an easy progress or a smooth journey without any obstacles or difficulties. It means that things are going well and progressing smoothly, often used to describe a situation or task that is going smoothly and without any problems. For example, if a student says, "I finished all my homework early, so now I can relax and enjoy some smooth sailing."
The expression 'smooth sailing' means easy progress. It is often used metaphorically to describe a situation wherein things are going well without complications or obstacles. The term originates from nautical language where it literally pertained to a boat or ship moving smoothly over water without any difficulties. For example, in a narrative, if a fisherman is described as having 'smooth sailing in his blue skiff,' it means his journey on the water is going unhindered and is relatively easy.
When comparing the other options provided in the question: 1) Easy progress, 2) Rough journey, 3) Difficult task, and 4) Challenging adventure, 'smooth sailing' is most accurately represented by the first option, which indicates a lack of hardship or challenge in moving forward. This is in contrast to a 'rough journey' or 'difficult task,' where one might encounter numerous challenges or issues that need to be overcome.
