<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm just beginning to get acquainted with
RSTanaysis, and have been trying to follow the examples provided on the site.
I'd like to know if the following analysis is a possible alternative to the one
appearing on p. 4 of the Introduction.</FONT></DIV>
<DIV><FONT face=Arial>The example: 1. Lactose and Lactase
(preparation)</FONT></DIV>
<DIV><FONT face=Arial>2. Lactose is milk sugar; 3. the enzyme lactase breaks it
down (elaboration)</FONT></DIV>
<DIV><FONT face=Arial>4. For want of lactase most adults cannot digest milk. 5.
In populations that drink milk the adults have more lactase, perhaps through
natural selection. (contrast)</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>If we're looking at writer's purpose, is it possible that
the relation between spans 4 and 5 is non-volitional result? The situation in
which most adults can't digest milk has resulted in a process of natural
selection in milk drinking populations. The 'contrast' relation doesn't seem to
express the implicit connection which gives these two spans
coherence.</FONT></DIV>
<DIV><FONT face=Arial>Thank you,</FONT></DIV>
