Respuesta correcta: A)My sister, who lives in Ponce, is visiting us next week.
A)My sister, who lives in Ponce, is visiting us next week.Correct! Both commas close around the extra information about the sister, which is not needed to identify her.
B)My sister who lives in Ponce is visiting us next week.No. With no commas the clause becomes defining, and it would claim you have only one sister who lives in Ponce.
C)My sister, who lives in Ponce, is visiting us next week next week.No. Repeating the time expression makes the sentence say the visit happens two times next week.
D)My sister who lives in Ponce, is visiting us next week.No. A comma after the subject but not before the clause leaves the extra information badly marked.
💡 Explicación
Both commas close around the extra information about the sister, which is not needed to identify her. In this item the choice that works is 'My sister, who lives in Ponce, is visiting us next week.', because it is the option that matches what the sentence and the task require.

Respuesta correcta: D)Her brother, who is a chef, opened a small bakery in Old San Juan.
💡 Explicación
The clause 'who is a chef' is extra detail, so a comma is needed before and after it. In this item the choice that works is 'Her brother, who is a chef, opened a small bakery in Old San Juan.', because it is the option that matches what the sentence and the task require.
Ver respuesta
Respuesta correcta: D)Her brother, who is a chef, opened a small bakery in Old San Juan.
A)Her brother, who is a chef opened a small bakery in Old San Juan.No. Only the opening comma is present, so the sentence never closes the extra information.
B)Her brother who is a chef, opened a small bakery in Old San Juan.No. Only the closing comma is present, so the extra information is never properly opened.
C)Her brother, who is a chef, opened a small bakery, in Old San Juan.No. The second comma separates a verb from its complement, which English does not do.
D)Her brother, who is a chef, opened a small bakery in Old San Juan.Correct! The clause 'who is a chef' is extra detail, so a comma is needed before and after it.

Ver respuesta
Respuesta correcta: A)The concert, which was sold out in an hour, took place at the stadium.
A)The concert, which was sold out in an hour, took place at the stadium.Correct! Commas on both sides mark the clause as extra information about the concert, not the thing being named.
B)The concert that was sold out in an hour took place at the stadium.No. Without commas the clause identifies which concert is meant, which makes it defining.
C)The concert, that was sold out in an hour, took place at the stadium.No. 'That' cannot introduce a non-defining clause, so the commas are not enough to save it.
D)The concert which was sold out in an hour, took place at the stadium.No. A single comma does not mark the clause as non-defining and leaves the sentence unbalanced.
💡 Explicación
Commas on both sides mark the clause as extra information about the concert, not the thing being named. In this item the choice that works is 'The concert, which was sold out in an hour, took place at the stadium.', because it is the option that matches what the sentence and the task require.

What is the effect of removing the commas from: 'The results, which were surprising, changed the plan.'
Elige una opción para comprobar tu respuesta.
Respuesta correcta: C)The clause becomes defining, so it would identify only the results that changed the plan.
💡 Explicación
Commas are what separate extra information from defining information, so taking them away changes the meaning. In this item the choice that works is 'The clause becomes defining, so it would identify only the results that changed the plan.', because it is the option that matches what the sentence and the task require.
Ver respuesta
Respuesta correcta: C)The clause becomes defining, so it would identify only the results that changed the plan.
A)The sentence becomes a question, because commas work like question marks.No. Commas never create or remove interrogative structure; a question needs auxiliary inversion.
B)The clause becomes a passive voice construction with the auxiliary 'were'.No. The passive voice is decided by the verb form 'were changed', not by punctuation.
C)The clause becomes defining, so it would identify only the results that changed the plan.Correct! Commas are what separate extra information from defining information, so taking them away changes the meaning.
D)The sentence keeps exactly the same meaning, since commas never change meaning in English.No. Commas are meaning-bearing in English, which is exactly why the non-defining clause needs them.
💡 Explicación

A)Her parents, whose house has a mango tree, live in Guayama.Correct! 'Whose' shows possession of the house, and the commas mark the whole clause as extra information.
B)Her parents, who house has a mango tree, live in Guayama.No. 'Who house' is not a valid subject and verb combination; 'whose' is required before a noun.
C)Her parents who house has a mango tree, live in Guayama.No. Only one comma is used, so the extra information is never closed, and 'who' is wrong anyway.
D)Her parents, whose have a mango tree, live in Guayama.No. 'Whose' cannot stand alone; it must be followed by the noun it modifies.

C)I called the doctor, to whom I explained the whole problem.Correct! After the preposition 'to', a non-defining clause referring to a person takes 'whom'.
D)I called the doctor, to that I explained the whole problem.No. 'That' cannot be preceded by a preposition to form a relative pronoun in this clause.

B)Extra detail about something already identified, which the reader could do without.Correct! Non-defining clauses add optional detail and always sit between two commas.
C)A list of every other object that appears in the same sentence.No. A relative clause carries one verb of its own; it does not list other objects.
