its "Voy a comer esta pizza."
Explanation:

A phenomenon (plural, phenomena) is a general result that has been observed reliably in systematic empirical research. In essence, it is an established answer to a research question. Some phenomena we have encountered in this book are that expressive writing improves health, women do not talk more than men, and cell phone usage impairs driving ability. Some others are that dissociative identity disorder (formerly called multiple personality disorder) increased greatly in prevalence during the late 20th century, people perform better on easy tasks when they are being watched by others (and worse on difficult tasks), and people recall items presented at the beginning and end of a list better than items presented in the middle.

Empezaron is the correct answer
Answer:
1. se
2. porque
3. te
4. Cuándo
5. ese
Explanation:
You must complete in the blanks.
1 and 3 are unstressed personal pronouns.
The unstressed personal pronouns are those that function as a direct or indirect complement (“Te lo dije”: "te" OI "lo" OD) or as part of the pronominal verbs: “me arrepiento”.
The forms of singular “me” and “te” and those of plural “nos” and “tus” are used without distinction of gender, and the same as a direct rather than indirect complement, so it is necessary to be able to distinguish when they are one and when another, attend not only to the nature of the verb, but also, in most cases, to the context.
2. is "because" (is giving a reason)
3. is asking "when"
5. is showing "that" what he/she wants.
