Suppose we have the relation schema R(A, B, C, D)with functional dependencies; F{A→B,B→C,C→D,D→A}, then R(A,B,C,D. at least is in(73).

B．2NF

C．3NF

D．BCNFThe construct eobegin Statement1; Statement2; coend means Statement1 and Statement2 are to be executed in parallel. The only two atomic actions in this construct are loading the value of a variable and storing into a variable. For the p

us two ABRs, ABR1, and ABR2, all in area 100. The branches connect to the ABRs using Frame Relay point - to - point subinterfaces. The verification plan lists the output of the show i p ospf database summary 10.100.0.0 command on a router B1, one of the branches.Which of the following is true regarding the output that could be listed for this command？（）

A. The output lists nothing unless 10.100.0.0 has been configured as a summary rou te using the area range command.

B. If 10.100.0.0 is a subnet in area 0, the output lists one Type 3 LSA, specifically the LSA with the lower metric when comparing ABR1‘s and ABR2‘s LSA for 10.100.0.0.

C. If 10.100.0.0 is a subnet in area 0, the output lists two Type 3 LSAs, one each created by BR1 and ABR2.

D. None, because the Type 3 LSAs would exist only in the ABR‘s LSDBs.

A: Very well, we have settled everything about this transaction, except the terms of payment.

B: As you know, we prefer the L/C 20 days in advance which expires 15 days after receiving the paking list.

A: I suppose you have known our financial standing and credit well now after our long-term cooperation．We know an irrevocable L/C can ensure that the seller gets payment duly．But, on the other hand, it would increase the buying cost．Therefore, could you consider giving us D/P this time？

B: I am sorry．But our rules only allow us to accept other terms of payment by L/C, although the buyer has had two or three transactions with us before.

A: But why not if you have known the buyer's credit after several deals？

B: We hope you can understand．We have got some serious lessons from the credulity．One of them was through D/P documentary collection．When the shipment worth US ＄50000 was effected, the buyer refused to make the payment．But we can do nothing with it．And that buyer had had one or two deals before this one.

A: I see．But the flexible terms of payment will definitely bring you more orders as well as facilitate the buyers' purchasing.

B: Sure．We don't mean we won't accept other terms of payment forever．As a matter of fact, we will do so when we have known well about the buyer's credit after a real long-term cooperation.

people go abroad every year．Some people even go on two or three holidays a year． There are two types of holiday-makers．The first kind always flocks to seaside resorts when they go on holiday．Their one and only aim is to have a good time by sun-bathing and putting their feet up．They are not a bit interested in local specialities．At mealtimes，if they can get a plate of British“fish and chips”，they’re more than happy!They spend their days in the sun-shine and their evenings getting drunk．and then sleep soundly．If this sort of person forgets to pack the suntan oil，he or she will undoubtedly come home as red as a lobster． The other type of holiday—makers goes to every country to increase their knowledge of for-eign lands．They make use of the chance to travel to improve their world knowledge．For them，going on holiday is educational．Consequently，this sort of travelers will move from p!ace to place every few days．If they visit lots of places in a short span of time，there is no way that they can get a proper feel of a place or fully appreciate the local food and wine． Whichever type of holiday chosen，everybody has the same aim：to put their work to the back of their minds，have as much fun as possible and come home happy and relaxed．

The aim of the first type of holiday-makers is__________ ．

A.to enjoy themselves

B.to enjoy good food

C.to have a good sleep
