La hoja de respuestas incluye la categoría.

Spanish often uses the definite article la more regularly than English uses the. Here, la hoja de respuestas means the answer sheet or the sheet of answers, referring to a specific sheet.

If you said just hoja de respuestas, that could work in some contexts, especially in headings, labels, or notes, but in a normal full sentence la is the most natural choice.

Because the sheet is for multiple answers.
Hoja de respuestas literally means sheet of answers, which is the normal way to say answer sheet.

Using respuesta in the singular would sound less natural here unless you were talking about a sheet for one single response.

It links the two nouns and shows what kind of sheet it is.

• hoja = sheet
• de respuestas = of answers

So hoja de respuestas is a noun phrase meaning answer sheet. Spanish often uses de where English uses a noun before another noun. Compare:

• libro de historia = history book
• tarjeta de crédito = credit card
• hoja de respuestas = answer sheet

Incluye is the third-person singular present form of incluir (to include).

It matches the subject la hoja, which is singular:

• la hoja = singular
• therefore incluye = it includes

So the grammar is:

• La hoja de respuestas = the answer sheet
• incluye = includes
• la categoría = the category

Because Spanish usually does not need a subject pronoun when the subject is already clear.

Here, the subject is explicitly stated as la hoja de respuestas, so adding ella would be unnecessary and usually unnatural:

• Natural: La hoja de respuestas incluye la categoría.
• Less natural here: La hoja de respuestas ella incluye la categoría.

Spanish normally avoids extra subject pronouns unless you want emphasis or contrast.

Here incluye most naturally means includes. In context, it suggests that the answer sheet has a category on it or as part of it.

Depending on context, English might translate it as:

• includes
• contains
• has

But the basic meaning is that the category is part of the answer sheet.

Because Spanish often uses the article when talking about a specific thing, especially when it is understood from the context.

So la categoría means the category, referring to a particular category already known or expected in the situation.

Without the article, categoría would sound more like a label, heading, or a very compressed style rather than a normal sentence.

Categoría is a feminine noun meaning category.

The written accent shows where the stress goes: ca-te-go-RÍ-a.

The accent is important because it tells you that the í is stressed and pronounced as a separate syllable from the following a. So it is not compressed into something like -ria in one syllable. Instead, it is pronounced more clearly as:

• ca
• te
• go
• rí
• a

Because it is the thing being included.

The subject is la hoja de respuestas because that is what performs the action of the verb:

• La hoja de respuestas = subject
• incluye = verb
• la categoría = direct object

In other words, the answer sheet does the including, and the category is what gets included.

It is a very common and natural expression, yes. It is the normal way to refer to an answer sheet.

Spanish often builds this kind of phrase with:

• a main noun
• followed by de
• followed by another noun

So while it is not a completely frozen phrase that never changes, it is definitely a standard and idiomatic combination.

Yes, that is grammatically correct, but it is slightly different in tone.

• incluye = includes
• contiene = contains

Incluye often suggests that something is one of the elements or parts listed on the sheet.
Contiene can sound a bit more literal, like the sheet physically contains that information.

In many contexts, both would work, but incluye is very natural if you mean the category is one of the items present on the form.

Yes, Spanish allows more flexibility than English, but the original order is the most neutral and natural:

• La hoja de respuestas incluye la categoría.

Other orders are possible for emphasis, but they are less neutral. For a learner, the original version is the best model to follow: subject + verb + object.

Yes. Both nouns are grammatically feminine:

• la hoja
• la categoría

That is why they take the feminine article la.

This grammatical gender does not necessarily mean anything about real-world gender. It is simply a property of the nouns, and adjectives or articles connected to them must agree with that gender.
