H D1 TS Q18 – Selective High School

I cannot get any answer when I dial my mother's phone number. She is either not answering her phone, or she has decided to stay away on holiday for an extra week. She must still be away. She would never let the phone ring without answering it.

Which of the following most closely parallels the reasoning used in the above argument?

If I want to remain fit and healthy, I have to watch my diet and take exercise. I want to stay fit, so I eat carefully and go running regularly. If Denise had carried on going to the gym and eating sensibly, she would never have got so run down. She did get run down, so she must either have given up her diet or stopped going to the gym. Joe is looking a lot fitter. Either he has cut down on his eating, or he has been out running every day. I know for a fact that Joe could not keep to a diet, so it must be from exercising. Anyone who swims over twenty lengths a day has to be pretty fit. Sheena swims thirty lengths a day. Therefore, Sheena must be quite fit.

Are you sure you want to leave?
