Directions to Solve
The logic problems in this set present you with three true statements: Fact 1, Fact 2, and Fact 3. Then, you are given three more statements (labeled I, II, and III), and you must determine which of these, if any, is also a fact. One or two of the statements could be true; all of the statements could be true; or none of the statements could be true. Choose your answer based solely on the information given in the first three facts.

In this type of problems, one should not consider any other fact.
Here, we cannot consider these to be relationship as well. So the other two children can be anything not just boys. No fact talks about boys. So the answer must be (D).

It should be 1 & 2.
Because out of 4- 2 are girls and also mentioned 2 have blue and 2 have brown eyes. That means one of the girls have blue.

1 can also be the answer because out of 4 children 2 children have blue eyes and half of the children are girls. So it could be at least one of the girl have blue eyes.

Cross-Genders do exist and are not classified as male or female, this is a possibility so. Therefore whether the remaining two children are boys, is unspecified.
