Explanation:

The sentence "Eugene Krabs tried to build a robot and a model airplane over the weekend." has correct capitalization (the name "Eugene Krabs" is properly capitalized) and correct punctuation (the sentence ends with a period, and there are no internal punctuation errors as the list of items being built is connected with "and" appropriately for a simple list of two items, so no additional punctuation like commas or semicolons are needed here).

Eugene Krabs tried to build a robot and a model airplane over the weekend.
