A lady in a red shirt and bikini bottoms is about to go surfing on a blue board in the ocean.
A woman is a good surfer.
You can not infer she is a good surfer.
Just because a lady in a red shirt and bikini bottoms is about to go surfing on a blue board in the ocean does not mean she is a good surfer.
Not all women are good surfers. We don't know if the lady is a good surfer or not; this could be her first time surfing.
