Can we draw the following hypothesis from the context (see options)? 

Context:

From March 4, 1993, when the damage control operation began, through the orchestrated in-house investigation, through the conceiving, conspiring, conniving and sanctioning of lies and misinformation, through the tampering with documents and the destruction of evidence, to the successful campaign to shut down the Somalia inquiry, people in high places for whom we are ultimately responsible have evaded accountability, escaped responsibility and eluded the efforts of properly constituted civilian authority - Parliament, government, a Royal Commission - to establish the truth.

Hypothesis: The investigation started a week previous to 03/11/93.

 a). Yes.
 b). It's impossible to say.
