Question

bird species by average mass
common name average mass (kg) capable of flight?
lesser rhea 19.6 no
dalmatian pelican 11.5 yes
andean condor 11.3 yes
northern cassowary 44.0 no
most bird species that are capable of flight weigh less than a kilogram (kg), which is not surprising considering the burden that extra body weight puts on a flying animal. but not all flying birds are so light, as we can see most clearly in the example of the ____________
which choice most effectively uses data from the table to complete the example?
a. northern cassowary, which has an average mass of 44.0 kg.
b. andean condor, which has an average mass below 10 kg.
c. northern cassowary, which has a higher average mass than the lesser rhea.
d. dalmatian pelican, which has an average mass of 11.5 kg.

Explanation:

The text states that not all flying birds are light - we need a flying bird with a relatively high mass from the table. The Dalmatian pelican is a flying bird with an average mass of 11.5 kg, which is higher than the typical sub - 1 kg flying birds. The northern cassowary and lesser rhea are not flying birds. The Andean condor's mass is 11.3 kg but the Dalmatian pelican's 11.5 kg is a better example of a relatively heavy flying bird from the given options.

Answer:

D. Dalmatian pelican, which has an average mass of 11.5 kg.
