In this problem we have the following three sentences:
→ Sophie sabe andar en bicicleta bien <em>(Sophie knows how to ride a bicycle well)</em>
→ Charlie saca muchas fotografías bonitas <em>(Charlie takes many beautiful photographs)</em>
→ Sophie y Charlie pasean en bote en el parque grande <em>(Sophie and Charlie take a boat ride in the big park)</em>
First.
To change each sentence into questions by changing the word order you need to exchange the order of the verb and the subject of the sentence, so:
1. Sophie sabe andar en bicicleta bien
Sabe which is a conjugation of the verb saber (to know) exchange the order with Sophie. You, as well, need to add question marks in the beginning and the end of the sentence, so the answer is:
<em>¿Sabe Sophie andar en bicicleta bien?</em>
2. Charlie saca muchas fotografías bonitas
Saca which is a conjugation of the verb sacar (to take, in this context) exchange the order with Charlie. By adding question marks in the beginning and the end of the sentence, the answer is:
¿<em>Saca Charlie muchas fotografías bonitas?</em>
3. Sophie y Charlie pasean en bote en el parque grande
Pasean which is a conjugation of the verb pasear (take a boat) exchange the order with Sophie y Charlie. By adding question marks in the beginning and the end of the sentence, the answer is:
¿<em>Pasean Sophie y Charlie en bote en el parque grande?</em>
Second.
By translating these questions we have:
1. Does Sophie know how to ride a bicycle well?
We use the auxiliary verb does since Sophie can be replaced by the pronoun <em>she. </em>In English, unlike Spanish, we use one question mark in the end of the question.
2. Does Charlie take many beautiful photographs?
As in the previous question we use the auxiliary verb does because Charlie can be replaced by the pronoun <em>he.</em>
3. Do Sophie and Charlie ride by boat in the big park?
In this case, we use the auxiliary verb do because Sophie and Charlie can be replaced by the pronoun <em>they.</em>
Third.
1. Sophie knows how to ride a bicycle well
<em>Sophie</em> can be replaced by <em>ella (she). </em>Sabe is the conjugation of the verb saber (to know) for the third-person singular in the simple present. Recall that the simple present is used to talk about ongoing actions.
2. Charlie takes many beautiful photographs
<em>Charlie</em> can be replaced by <em>él (he). </em>Saca is the conjugation of the verb sacar (to take, in this context) for the third-person singular in the simple present.
3. Sophie and Charlie take a boat ride in the big park
<em>Sophie and Charlie</em> can be replaced by <em>ellos (they). </em>Pasean is the conjugation of the verb pasear (to take a boat) for the third-person plural in the simple present.
