Standardise each of the following arguments. State whether any premises on the same level are linked or convergent.

(i) If Smith made it to the summit of Mt Everest he would have evidence and he does not have evidence because all his climbing companions deny his achievement and you can tell the photos he has provided were taken at Thredbo.  Therefore, Smith did not make it to the summit of Mt Everest. 

1.  If Smith made it to the summit of Mt Everest he would have evidence

2.1 All his climbing companions deny his achievement

2.2 The photos he has provided were taken at Thredbo

2. He does not have evidence

C. Smith did not make it to the summit of Mt Everest                                                                                                                                    

1. and 2. are linked.  2.1 and 2.2 are convergent.

(ii) It's dangerous to travel on trains alone at night.  There are no transit police on trains after 9 PM to protect you because there are not enough passengers to make revenue-raising feasible.  Also, many vagrants use the trains at night to sleep on, and when in groups, vagrants can be dangerous.

1.1 There are not enough passengers to make revenue-raising feasible

1. There are no transit police on trains after 9 PM to protect you

2. Many vagrants use the trains at night to sleep on

3. When in groups, vagrants can be dangerous

C. It's dangerous to travel on trains alone at night

1. is convergent with 2. and 3. which are linked.
