Q-1: Based on the graph above what social media platform would the user be using?

• Instagram
• This is incorrect due to the graph not being directed.
• Twitter
• This is incorrect due to the graph not being directed.
• Reddit
• This is incorrect due to the graph not being directed.
• Facebook
• Correct, because the Graph is undirected.

Q-2: Match the correct NetworkX code piece to the correct description.
• G
• This variable is a DiGraph object that contains no nodes and no edges.
• add_node
• This method adds nodes.
• nodes
• This method gets a list of nodes.
• Nodeview
• This class can be used in a for loop or it can make a list.
• Edges
• This method gets a list of edges.
• Draw_circular
• This method arranges the nodes in a circle and connects them with edges.

Please construct def complete_graph:

        def make_complete_graph(n):
---
    G = nx.Graph()
    ---
    nodes = range(n)
    ---
    G.add_nodes_from(nodes)
    ---
    G.add_edges_from(all_pairs(nodes))
    ---
    return G
