Yes, it is true that a context-free language is a superset of a regular language.
No, it is not necessarily true that if language A is regular and language B reduces to A, then language B is also regular.
Yes, it is true that every finite language is regular.
The keyword "pumping lemma" can be used to prove that a language is regular by showing that any sufficiently long string in the language can be divided into parts that can be repeated or "pumped" to create more strings in the language. If this property holds true for a language, it indicates that the language is regular.
The language defined by the regular expression "add" is not a regular language because it requires counting the number of occurrences of the letter "d," which cannot be done using a finite automaton, a key characteristic of regular languages.
Yes, it is true that if a language is undecidable, then it must be infinite.
No, it is not necessarily true that if language A is regular and language B reduces to A, then language B is also regular.
Yes, it is true that every finite language is regular.
A sample is a subset of the population.

Yes web pages are written in 'html' (Hyper Text Mark-up Language), which is an implemented subset of 'sgml' (The Standard Generalized Markup Language (ISO 8879:1986 SGML).
a is a subset of b
That's false.
