To replace the accompanying noun, write a direct object. They can be replaced if it is <u>masculine</u> it is "lo" (singular) or "los" (plural) and if it is <u>feminine</u> it is "la" (singular) or "las" (plural).
In this case "los" is used because "<u>los huevos</u>" is a word that is <u>masculine</u> and <u>plural</u>, while "<u>las recetas</u>" is written "las" because the word is <u>feminine</u> and <u>plural</u> as well.
Now that you have worked through a lot of material that includes these basic patterns, and you have compared grammatically correct and incorrect sentences, write down what you think is a rule that could explain what makes a sentence grammatically correct or not. For example, you might write something like: "verbs always match nouns in number, and they usually come before the noun." In other words, make your best guess for the grammar rule that makes sense out of the pattern(s) you see in the phrases you have been working with. Review if you need to, and you might briefly check your hunches against the sentences you have been working with in this or previous modules. Keep in mind that what you're after is your hunch, not a grammar rule from a text book.
