The moral framework has a religious basis which is based on divine revelation	The moral framework has a religious basis which in turn is based on divine revelation.

In academic writing we may want to show that the relationship between B and C follows on the relationship between A and B. Here for example, A (the moral framework) is based on B (religion), and B (religion) is based on C (divine revelation). The expression in turn can be very useful to make clear this sequence of relationships. Here are some examples. In each one, try to identify A, B & C, and the words that show the relationships between them:

1. Radioactive nickel-56 decays quickly to cobalt-56, which in turn decays into stable iron-56 over a period of several months.
2. No pesticides have ever been used on the parkland through which the stream flows, so there are still plenty of aquatic insects to feed the fish. They in turn feed the electric blue kingfisher, which has disappeared throughout much of this country.
3. Between July and September 1988 the expenditure meaure of GDP was 5.5 per cent lower than the income measure, which in turn was 5.5 per cent lower than the output measure.
4. It has recently been shown that the organism H. pylori, which resides in the stomach wall, can stimulate abnormally high levels of gastric acid. The acid in turn causes irritation and inflammation.
5. Increased carbon dioxide improves plant growth.. This increases crop yields, in turn reducing carbon dioxide and redressing the atmospheric balance.
6. Declining funds have forced many youth clubs and centres to reduce activities forced many youth clubs and centres to teduce activities, cut staff, and even close. That in turn has meant fewer places for young people to turn to in times of trouble.
7. He claims that schools in the USA are organised like factories. Every period is the same length of time; children move mindlessly from one class to abother, and they are treated impersonally by teachers, who are in turn told what to do by a top-down bureaucracy.
8. The algae are a food source for zooplankton, which in turn feed tiny shrimps and fish, which in turn feed the Charybdis smithii.''

Two simple questions to think about:

• How are citatons 1-3 different from citations 4-7?
• How is citation 8 different from all the the other citations?

In the following citations, try matching the text up to in turn with what follows. The first match is A-H. Can you find the others?

A	Energis is owned by the National Grid Company, which in turn	A	was struck by a Ford Orion car.
B	Public investment leads to higher demand and higher incomes, which in turn	B	is owned by the 12 regional electricity companies.
C	The coach was immediately hit by a British Telecom van, which in turn	C	was related to the hours of bright sunshine.
