假定经济满足Y=C+I+G，且消费C=800+0.63Y，投资I=7500-20000r，货币需求L=0.1625Y-10000r，名义货币供给量6000亿元，价格水平为1，问当政府支出从7500亿增加到8500亿时，政府支出的挤出效应有多大请结合中国财政政策的实际情况加以分析。

We have already covered the topic of network addresses. The first  (1) in a block (in classes A, B, and C) defines the network address. In classes A, B, and C,if the hostid is all ls,the address is called a direct broadcast address. It is used by a(2) to send a packet to all hosts in a specific network. All hosts will accept a packet having this type of destination address. Note that this address can be used only as a (3) address in an IP packet. Note also that this special address also reduces the number of available hostid for each netid in classes A,B，and C． In classes A, B, and C, an address with all ls for the netid and hostid (32bits) define a (4) address in the current network.A host that wants to send a message to every other host can use this address as a destination address in an IP packet. However, a router will block a packet having this type of address to confine the broadcasting to the (5) network. Note that this address belongs to class E.
