1. The national rank in Sales Revenue and national rank in Sales Volume are positively correlated.
Sort the table as per increasing order of national rank in Sales Revenue and you will find the national rank in Sales Volume too increasing. Hence, both are positively correlated. YES

2. If no company had less than 1% of National Sales Revenue, then there were only two companies contributing to National Sales revenue in Electronics.
Check the row of Electronics, company Y has 49.5% share and yet it is 2nd overall in national ranking. For sure, there is another company that has greater than 49.5% share.
Combined, both these companies have greater than 49.5+49.5 or 99%, so less than 1% is unaccounted for. But we know no company had less than 1% of National sales revenue, so only these two countries contributing, one with 49.5% and other with 50.5%. YES

3. There were at least four companies dealing with clothing in country X.
We have ranking of company Y 3rd and 2nd in national ranking. So, we cannot say whether there are more number of companies below Y. We just know that there are at least 3 companies. NO
