(1) Carson's sister Loraine , who got married 2.5 years before Carson and Joan got married, got married in 1964
(2) Carson and Joan's 16th wedding anniversary was in 1982


Statement 1 is insufficient. Let us consider 2 cases.
Case i: Loraine got married in the June of 1964, then Carson would have married in December of 1961.
Case ii : Loraine got married in July of 1964, then Carson would have married in January 1962.
Hence we cannot conclusively decide in which year Carson got married from Statement 1.

Statement 2 is Sufficient:
Carson and Joan's 16th wedding anniversary was in 1982. Hence they would have married 16 years before!
(Do the math!)

Hence B is the answer.

Hi All,

We're asked for the year that Carson and Joan got married. While this is an older question, it's a great example of how you have to be 'thorough' while thinking about the possibilities.

1) Carson's sister Loraine , who got married 2.5 years before Carson and Joan got married, got married in 1964.

With Fact 1, we have to consider which MONTH we're discussing. For example:
IF... Loraine was married in JANUARY of 1964, then Carson and Joan got married in JULY of 1966.
IF... Loraine was married in DECEMBER of 1964, then Carson and Joan got married in JUNE of 1967.
Fact 1 is INSUFFICIENT

2) Carson and Joan's 16th wedding anniversary was in 1982

The 16th anniversary is 16 FULL YEARS, so regardless of the month that Carson and Joan were married, the anniversary would be in the SAME month. Thus 1982 - 16 years = 1966 was the year they were married.
Fact 2 is SUFFICIENT

Final Answer:

GMAT assassins aren't born, they're made,
Rich
