Explanation:
To answer this exercise we first have to know what <u>REFLEXIVE VERBS</u> are because it is the main theme of our sentences.
<h3><em>
REFLEXIVE VERBS</em></h3>
They are a special kind of CONJUGATED VERBS that are transitive. It means that <u>the action expressed by the verb is affecting the subject of the sentence.</u> Thus, the person who does the action is the same person who receives that action.
<u>For example:</u> <em>Yo me peino</em> (I comb my hair); here I’m the person who is doing the action of “combing”, but my own hair is who is being combed, so I do and receive the action of the verb at the same time.
Verbs related to<u> personal routines</u> (for example combing, making up, dressing up, washing, having a bath, etc.) are commonly <u>REFLEXIVE VERBS</u>.
<u><em>GRAMMATICAL RULE:</em></u> It is really important to notice that REFLEXIVE VERBS are always accompanied by REFLEXIVE PRONOUNS, which are in charge of expressing who is receiving the action.
<h3><em>REFLEXIVE PRONOUNS</em></h3>
- Yo –Me
- Tú- Te
- ÉL/ella/usted- Se
- Nosotros-Nos
- Vosotros-Os
- Ellos-Se
Now, here we have the answers, please focus your attention in the conjugated verb and the reflexive pronoun that is always next to it. Each example has the same conjugated verb but one sentence is reflexive and the other isn’t.

Answer:
a problem is researchable only if it can be scientifically proven
Explanation:
In science, a problem can be defined as a statement, condition, difficulty or question which is investigated by using the scientific method. In the scientific method, first is required to raise a possible explanation or 'hypothesis', which is based on objective inferences. Second, from this hypothesis, it is possible to make predictions which are subsequently proved or rejected by carrying out experiments and/or empirical observations in order to finally obtain results and conclusions about the researchable question.
