This might have been the only day when that explanation sounded remotely plausible.

Such an explanation sounded altogether too unscientific; but he could not think of any other at the moment.

In hindsight, the explanation for both of them sounded similar.

His whole explanation sounded like just another made up one, and just as wrong.

Neither does another explanation sound right, that he was trying to redeem himself for his earlier failure.

His explanation sounded true, but he was still cut off from her.

His explanation of why he wanted it didn't sound very convincing to me.

"I'll tell you what it did," he says, but the explanation sounds like another not.

But which explanation sounds like it has a better chance of being true?

There's often a nagging feeling that the explanation sounds phony even though true.
