Q:

How to centre text?

I want to write some text in the centre like the following? 

EDIT:
Sorry the picture seems caused confusion. I retracted some text for privacy. What I want is just how to center the text in the same way in the picture. To make the alignments like in the picture.
But I do not want to make the highlight or retraction. Just the centering.

A:

\documentclass{article}
\usepackage{lipsum,stackengine}
\setstackEOL{\\}
\begin{document}
\lipsum[1]
\begin{center}
{\textbf{\Longstack[l]{
  Question 1: Can we archive the blacked out text\\
  so that it can be left aligned?\\\\
  Question 2: Can we archive the blacked out text\\
  so that it can also be centered?
}}}
\end{center}
\lipsum[2]
\end{document}
