Algorithm questions.

1.When choosing an algorithm for the shortest path between two nodes in an unweighted graph, should we use Breadth First Search or Depth First Search ?

2. When choosing a data structure to store a graph for an algorithm, how should we store the graph knowing that the graph is dense and this algorithm needs to determine many times if two nodes are directly connected ? Should it be an Adjacency Matrix or an Adjacency List ?
