Questions 21-30
21/22 B/D (in any order)
Distraction A: The tutor asks: ‘So there’d be public access?’
but this is not discussed as a problem; C: Although the student mentions time with regard to saving money: ‘they would save that much in approximately five years’, no time scale is discussed with regard to construction.

23/24 A/E (in any order)
Distraction B: Although ‘drainage issues’ are mentioned, both student and tutor agree that they ‘have been well understood for quite a long time’ (i.e. they are not ‘recent’);
C: The student talks about tank designs but not as a ‘recent development’ (‘fairly conventional storage tanks, the kind that have been in use for decades’); D: They agree on the need ‘to use lightweight materials’ but these do not need
to be modern. The tutor suggests ‘You can even use quite traditional ones such as wood’ and the student comments that these Took good’ and aren’t ‘too heavy’.
