I only count 4 queries:

www.yahoo.com.ar to ROOT returns delegation to AR servers
www.yahoo.com.ar to AR server returns delegation to ns#.yahoo.com
www.yahoo.com.ar to ns#.yahoo.com returns CNAME + delegation to 
yf#.yahoo.com
hp2.latam.g1.b.yahoo.com to yf#.yahoo.com returns second CNAME and final 
answer

All the delegations included glue records.
