<DIV><FONT size=2 face=Arial>Language! Wonderful thing.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>We do need to be careful and conscious of the
different ways people express themselves.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>My favorite example involves days of the week. Eg
"I'll meet you at 10am next Saturday." Please note I am writing this on
Wednesday 4 May.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Some interpret "next Saturday" as
Saturday 7 May, while others understand it to mean "Saturday of next week", ie
Saturday 14 May.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>So back to the algorithm! In such a question, the
wording needs to be unambiguous, eg "in less than 10 seconds" or "in
10 seconds or less". </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>We all write things from our own perspective and we
need others to point out possible misunderstandings - as you have done this
time. Thank you.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Hopefully with exams this problem is addressed by
the checking by the exam writers themselves, followed by ESL checking and then
the use of Sitter/Vetters. But still problems do occur and are then dealt with
at the exam marker training sessions that involve many more people.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Second opinion? "Within" means inside and should
perhaps be interpreted as <10. Just my opinion :-)</FONT></DIV>
