LR(k) grammars are the subclasses of context free grammars. If G1 is an LR(k) grammar then there must be a deterministic pushdown automata that accepts L(G1). So, LR(k) grammar is a deterministic context free grammar.
If G1 is an LR(k) grammar where k>1, then there must be an equivalent grammar G2 which is LR(1). Therefore, statement 2 is also true.
In LR(k) grammars L stands for the left to right scanning of the input strings and 'R' denotes the rightmost derivation and k is the number of look ahead input symbols.
To get a right derivation tree for the given sentence 's' , we can start with s and replace it with a substring s1 and repeat the process until we get the same start symbol.
