If they spend all night writing computer programs, laurence can write 10 programs while carrie anne can write 5. if they spend all night making sunglasses, laurence can make 6 while carrie anne can make 4. given this information and supposing laurence and carrie anne have constant opportunity costs, we know that:

Laurence has an absolute advantage in both programs and sunglasses

Explanation:

            "Absolute advantage" is used in economic terms which means the capability of an individual or organisation to produce or have an advantage of producing more product or services using the equal amount of resources is termed as having "absolute advantage" for that individual or organisation.

            Here while writing programs, Laurence wrote 10 programs while Carrie Anne can wrote 5 programs.

            And  while making sunglasses, Laurence made 6 sunglasses while Carrie Anne made 4 sunglasses.

           Thus it is seen that in both the cases, the productivity of Laurence is more than the productivity of Carrie Anne when using same amount of time.

Thus the answer is

"Laurence has an absolute advantage in both programs and sunglasses".
