The key answer of exercise 3

a)

Question 1

• The six numbered sentences could be confusing because they either contain numerous subordinate clauses and examples and / or it's difficult to match the subject and the main verb.

Question 2

1. the decisions which / that people have the most difficulty dealing with are often the smaller ones.
2. the immensely successful self-help author and social psychologist Dr. Shad Helmstetter in his book Choices: Discover your 100 Most Important Life Choices invited us to reflect on the decisions which / that we make, drawing our attention to the way that / which everyday choices are the ones that have the greatest impact on our lives and indeed on who we are, rather than the 'biggies' such as career / partner / home-related ones.
3. Helmstetter's list, which ranges from decisions about 'Your posture' to 'Who you spend most of your time with' or 'How you spend your holidays', comes as good news for those who agonise over the decisions which / that they make.
4. People who are judged negatively for their reluctance to make simple decisions may find some validation in Helmstetter's book.
5. By exploring so many disparate examples of everyday decisions which have consequences of greater significance than one might think at the time, he reminds us that in fact we are the ones in control of our destinies.
6. It's not only actions such as what time we go to bed or how often we lie that are under our control, but also how much patience we have, what makes us angry and even how happy we are.
