There is no end to the magic within this circle of the round world we live in. The greatest magicians today are still the physicists and chemists, the mathematicians and astronomers: the wise men seeking the answers to the riddles of earth and universe. But ________ (1) of them can tell us how it is we can walk_________ (2) a floor.
1. a. not one b. not any
I think both are correct. 'a' lays stress on every single person. 'b' lays stress on people as general. Am I right?
Given the three semantic choices: Not
one of them/Not
anyone of them/Not any of them, I'd choose (a) 'not one'. I wouldn't chose (b) 'not any' because 'any' here is not short for 'anyone'. :(
2. We can say 'to walk along the street'. That means we walk forward on the street. Am I right?
2. a. across b. along
The correct answer is 'a' . Does it mean to walk from one side of the earch to the other? Since it mentioned 'the round world' across and along should be the same. So I think 'b' is OK and maybe even better. If 'floor' means the surface of the earth why 'a floor'?
I'd choose (a) 'across' based on
Process of Elimination. That is, I wouldn't choose (b) because 'along' means, beside, through; alongside.
3. I didn't know been doing can refer to past tense. My grammar books say 'have been doing sth' means 'some act which began in the past lasts till present'. Or when we don't indicate the time the action took place. That why I got confused. Now I see.

I have lost count of the times we have been filming police officers on the street when local residents have come up to us and told us it is the first time in weeks they have seen police in the area.
I question is why perfect continous tense is used? Since it happens many times can I use simple present continous tense and write the sentence this way 'I have.....times we are filming ......'?
Try,
I've lost count of the times we have been filming (at the time=continuous/progressive) on the street when residents have come up to us....
Note, have been filming: be
en = past
