Identify the main idea of this paragraph: This ship is carrying kala fever serum to Group One on Woden. Their own supply was destroyed by a
tornado. Group Two-the crew your brother is in-is eight thousand miles away across the Western Sea and
their helicopters can't cross it to help Group One. The fever is invariably fatal unless the serum can be had in
time, and the six men in Group One will die unless this ship reaches them on schedule. These little ships are
always given barely enough fuel to reach their destination and if you stay aboard your added weight will
cause it to use up all its fuel before it reaches the ground. It will crash, then, and you and I will die and so will
the six men waiting for the fever serum.
The kala fever is a disease that kills men in space, particularly those on Woden. The EDS pilot knows about this
fever from experience.
The EDS must reach its destination because the lives of six men depend on it. If Marilyn stays on board, the ship
will not reach them.
O Marilyn's brother chose to work for Group Two, and that took him far from Woden. On Woden, a tornado
destroyed precious supplies.
A tornado destroyed the fever serum that was on its way to Woden. Woden needs the serum as soon as
possible.
