1. Which word best completes the sentence? Carolina es_______ hermana mayor.

A. una
B. ella ****
C. un
D. el

2. What type of islands are the Seychelles islands?
A. continental
B. barrier
C. volcanic ****
D. coral

To answer the first question, "Which word best completes the sentence? Carolina es_______ hermana mayor," you need to determine the correct word to fill in the blank.

In this case, "Carolina es" means "Carolina is," and you're looking for the word that completes the sentence. Let's examine the options:

A. una
B. ella
C. un
D. el

The correct answer is B. ella. The sentence translates to "Carolina is _____ hermana mayor." Since "ella" means "she" in Spanish, it makes sense in this context.

To answer the second question, "What type of islands are the Seychelles islands?" you need to know the characteristics of the islands to determine the correct answer.

A. continental
B. barrier
C. volcanic
D. coral

Let's break down each option:

A. continental: Continental islands are formed as a result of rising and falling sea levels on continental shelves. The Seychelles islands are located in the Indian Ocean, far from any continental shelves, so this option is unlikely.

B. barrier: Barrier islands are long, narrow islands that are parallel to the mainland coast and often serve as barriers against the open sea. The Seychelles islands are not known as barrier islands, so this option is unlikely.

C. volcanic: Volcanic islands are formed by volcanic activity. The Seychelles islands primarily consist of granitic and coral islands, which are typically formed from volcanic activity, so this option is likely the correct answer.

D. coral: Coral islands, also known as atolls, are formed from carbonate deposits by corals and other marine organisms. While coral islands are present in the Seychelles, they are not the dominant type of island, so this option is unlikely.

Based on this analysis, the correct answer is C. volcanic. The Seychelles islands are primarily volcanic in nature.

1. The word that best completes the sentence "Carolina es _______ hermana mayor" is B. ella.

2. The Seychelles islands are C. volcanic islands.
