Please read the following sentences:

Women who ate nuts more than five times a week were about one third less likely to suffer from coronary heart disease than were those who ate no nuts at all.

From this it can be inferred that the following will be correct:


1. X was less likely to do M than was Y who like to do N.

2. X was less likely to do M than Y was.

=> If there is nothing more after Y, we can use the verb 'was' after Y.

=> if there is something that modifies Y after Y, we should use the verb before Y. See the example 1.

Am I right?
