How many signals do you expect to be observed from a DEPT-90 spectrum of the compound below?

Why is it that D hydrogens have a higher chemical shift than the E hydrogens? Aren't the D hydrogens less shielded than the E hydrogens which have carbons surrounding on both sides? And less shielding means higher chemical shift required?

need soon both

#6) Using the following spectra and other information provided, identify the compound. Assign pertinent peaks in the spectra. Label the peaks on the spectrum and place the structure of the compound in the box on the right side of the spectrum - Identify correct compound - label proton spectrum - label carbon spectrum
