Answer 1

For completeness, I'll write up the answers in the comments: \begin{align*} &a)\qquad (\forall\,x)[(\text{Likes}(\text{rabin},\text{CSit})\;\land\;\text{Likes}(\text{rabin},x))\implies x=\text{CSit}] \\ &b) \qquad (\forall\,x)[\text{TypeOfCourse}(x)=\text{Science}\implies\text{Hard}(x)] \\ &c)\qquad (\forall\,x)[(\text{Course}(x)\;\land\;\text{TypeOfCourse}(x)=\text{CSit})\implies\text{Easy}(x)] \\ &d)\qquad (\forall\,x)[\text{CSC101}(x)\implies\text{CSit}(x)] \\ &e)\qquad (\forall\,x)(\forall\,y)[(\text{DNA}(x)=\text{DNA}(y)\implies x=y)\;\land\;\text{Parent}(x,y) \implies\text{DNAIsDerivedFrom}(y,x)]. \end{align*}
