Synthesising Complex Aromatic Compound Synthesize the following compound using only toluene as the carbon source-
  


I have never done something like this before and I have no clue on how to start. 
I am even more confused by the fact that the top two phenyl groups are meta substituted despite having a methyl group which is suppose to be ortho and para directing. 



From an answer below it states I need to use Friedel–Crafts acylation. However I am not entirely sure how to do this. This is my guess:

Convert toluene into benzoic acid using $\ce{KMnO4}$ and then react half of it with $\ce{SOCl2}$ to form $\ce{C6H5COCl}$. Then react that with the other half of the benzoic acid followed by Wolff–Kishner reduction to form the below molecule:



After this, I am not sure how to chlorinate it so that I do another acylation.
An alternative approach might be something like this. The tertiary alcohol product with two identical groups suggests that a Grignard reaction with an ester might be a useful step.
