explanation: "abundant" refers to abundance or great quantity, "scarce" refers to not enough, and "abundant" is the opposite of "scarce". "thoughtful" refers to carefully considering other people's mood and condition, giving care, and "rough" refers to roughness and rudeness, and there is no obvious logical relationship between "thoughtful" and "rough". "ugly" refers to bad-looking and unfavorable, and there is no obvious logical relationship between "delicate" and "ugly". "constrained" means to restrain oneself too much, which seems unnatural, while "casual" means to behave at one's will. "constrained" and "casual" have the opposite meaning. "uplifting" means cheering up, while "calm" means composed and unsentimental. "uplifting" and "calm" do not have opposite meanings.
