The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Let \(A = \{a, b, c, d, ..., z\}\) be the set of lower cased English letters.
Let \(S = \{a, b, ab, cd, ae, xy, ord, ...\}\) be the set of all strings using \(A\) as an alphabet.
Given \(s\in S\), \(N(s)\) is the number of vowels in \(s\).
For example,\(N(algrzqi) = 2\), \(N(bebebe) = 3\).
We say \((s, t)\) belongs to relation \(R\) if \(N(s) \leq N(t)\).
Which of the following statements are true (more than one answer can be correct) ?
A. \(R\) is reflexive.
B. \(R\) is transitive.
C. \(R\) is symmetric.
D. \(R\) is not an equivalence relation.
