When you click into this decision you do not physically select which 2 new products you want to sell. What you are doing is viewing the available options of new products and mentally deciding which 2 new products you want to sell later in the round.
The scenario is that the boss wants to see if adding two more products to the site will increase sales and profits. Review the products, pricing and margins and select which two additional products you think will sell well online. Don't forget to also check the keyword data you have around those products you would like to begin selling. Search volume usually correlates with demand for a product.
There will be other decisions in the round that will allow you to add the new products you decided to try and sell.
All you need to do to check off this decision is click into it and review the products.
