a (I should not buy a car at the moment) 1. (I have just lost my driver's licence) 2 and, besides, (I cannot afford it) 3.
There are no link words that might signal the conclusion or premises. However, of the three claims, claim 1 is the obvious conclusion. If claims 2 or 3 were the mainp - softvnn.com conclusion, then the argument would make very little, if any, sense at all. In this case, the premises do not add together. While the word and' might suggest they do, either premise on its own would be sufficient to support the conclusion. Hence they are independent of one another in the diagram. (See chapter 4.)

This example should be easier than the first. This time there are two linking phrases, which clearly show the conclusion and one of the premises. Claims 1 and 2 are dependent on one another, meaning they must be 'grouped' together. (See chapter 4.)

Given that (we are all roughly equal in our job performance) 3, I would have to conclude that (a university education really helps one to get ahead in a career) 4.

The trick here is to avoid being fooled by the punctuation: the first three claims are all dependent premises, despite being spread over three sentences and despite the lack of clear signals for the first two claims. See the section 'Special function of premises' in chapter 4 for a discussion of how one claim
