Some butterflies have a bright pattern of colors on the upper surface of their wings which show when they fly, but when they rest on a tree or leaf they close their wings. On the undersides of their wings there are green and brown markings which look like the tree or leaves. They are then difficult to see. The best example of this is the Dead Leaf Butterfly. When its wings are closed, it looks like the holes in a dead leaf. When a bird is chasing a butterfly, and it closes its wings, it seems to have disappeared completely.
Many butterflies have round marks on their wings that look like eyes. When they are resting, and their wings are folded, these cannot be seen. when a bird sees one, and begins to attack it, the butterfly opens its wings. The bird thinks that it sees two eyes staring at it, and frightened, it flies away.
Which of the following is likely to be the most brightly colored?
A.A male butterfly in a hot country.
B.A female butterfly in a hot country.
C.A dead leaf butterfly with its wings closed.
D.A large, heavy butterfly.

When the system upon which a transport entity is running fails and subsequently restarts, the(1)information of all active connections is lost. The affected connections become half-open, as the side that did not fail does not yet realize the problem.
The still active side of a half-open connections can close the connection using a(2)timer. This timer measures the time transport machine will continue to await an(3)of a transmitted segment after the segment has been retransmitted the maximum number of times. When the timer(4)the transport entity assumes that either the other transport entity or the intervening network has failed. As a result, the timer closes the connection, and signals an abnormal close to the TS user.
In the event that a transport entity fails and quickly restart, half-open connections can be terminated more quickly by the use of the RST segment. The failed side returns an RST i to every segment i that it receives. When the RST i reaches the other side, it must be checked for validity based on the(5)number i, as the RST could be in response to an old segment. If the reset is valid, the transport entity performs an abnormal termination.
