Most questions caused little (1)..it was rather like dancing, where both partners know 
how to avoid (2).on each other’ s toes.
But, ‘when are you going home?’ was a question I (3).to answer, whenever (4)..my
life and the direction it seemed to be (5)...In the last ten years, I had lived in a dozen 
countries. And I had travelled through dozens more; usually in (6)..of a purpose or a 
person; occasionally to see the attractions.

Running speed
Ellte competitors like the Jamaican Boit have regularly been clocked running at nearly 
45 kilometres per hours. Such speed would have seemed (9) (believe)..not so long 
ago. Scientists now suggest that humans can move (10) (consider)..faster than even 
that, perhaps, as fast as 65 kilometres perhour.
For years, it was assumed that simple muscle power determined human speed, but 
recent research suggest otherwise. The most important (11) (limit)..factors appears to
be how quickly the muscles can contract and thus (12) (minimum)..the time a 
runner’ s foot is in contact with the ground. 
Is our athletic abiliy inherited? Researcher Alun Williams has (13) (identity).. twenty-
three inheritedfactors that influence sporting performance, such as the (14) (efficiency)
.use of oxygen, and strength. As the world population rises, predicts Williams, the 
(15) (possible).....of there being someone with the right genes for these twenty- three 
(16) (character)..will increase noticeably and thus faster runners are likely to emerge 
in future.
