Folks,
Any thoughts on the following:
Art historians are using a process known as infrared scanning in analyzing the Mona Lisa to determine
if has been altered since completion and if Leonardo da Vinci first sketched the figure in black, as done by artists of the time.
(A) if has been altered since completion and if Leonardo da Vinci first sketched the figure in black, as done
(B) if it had been altered since completion and if Leonardo da Vinci first sketched the figure in black, a practice employed
(C) whether it has been altered since completion and whether Leonardo da Vinci first sketched the figure in black, a practice employed
(D) whether it was altered since completion and whether Leonardo da Vinci first sketched the figure in black, as was done
(E) whether it had been altered since completion and whether Leonardo da Vinci first sketched the figure in black, a practice done
++++
The OA is (c). I would appreciate if someone can provide further insights into the following fundamentals based on the above question:
a)What is the difference b/w "has been" and "had been"?Why is "has been" more appropriate compared to "had been" in this case?
b)Why should we add the word "whether" in (C)?What purpose does it serve?
++++
Tx.
Anna
