could you explain to me how you calculated that change ??

For country Y during 2004, it is at about 8.5% and 5% during 2006, or am I missing something? I tried to upload the attachment where I circled it but it won't let me.

Hi There!

I think there are certain restrictions on this i.e either you have to be a member for a year or create 20 posts, you won't be able to post before completing either of the two.

I also thought the answer is D. As we can derive from the graph that in 2004, country X was on 8.5% of unemployment and then decreased to 5% in 2006. Thus giving us a change of 3.5% while option has a smaller increase.
Option B suggests Country X, from 2003 to 2004 which is 3% and 5.5% respectively. Thus the change is of 2.5% which is lesser than that derived from option D.
Other options are clearly eliminated as they have smaller change comparatively.
Is something wrong with my approach because I don't understand how the answer is option B?

Country X is the red line

Country Y is the blue line

Country X in 2003 was at 3 and in 2004 was at 5

% change is = \(\frac{change}{original}\)*100

% change = \(\frac{5.5-3}{3}=83.3\)% in change

Country Y in 2004 was 8.5 and in 2006 was 5

% change = \(\frac{8.5-5}{8.5} = 41.1\) % in change

\(83.3 > 41.1\)

B is the answer.

I do not know why is so complicated. It is there ...........

I would like to add an alternative approach also

You just need visualization of the graph



the red portion is way steeper than the blue portion. Clearly

The change in B > of the change in D
