This question stands for demonstrative adjectives, such as <em>este, ese and aquel</em>. So these adjectives demonstrate a quality about the noun they modify. Here that quality is the <em>location</em> in respect to the speaker or the listener. <em>Este </em>is used to point out something near to the speaker in space or time. Since <em>arena </em>is a feminine noun, <em>este </em>changes to <em>esta </em>for matching this noun in gender. Therefore:
IN SPANISH:
<em>Esta arena es bonita</em>
IN ENGLISH:
<em>This sand is beautiful</em>
<h2>2) Right answer</h2><h3>orca</h3><h3 />
The killer whale or orca (also kwon as <em>Orcinus orca</em>) is a toothed whale that belongs to the oceanic dolphin family. This animal belongs to the class <em>Mammalia.</em> This is a type of a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, <em>the secretion of milk by females</em> for the nourishment of the young.
<h2>3) Right answer</h2><h3>loro</h3><h3 />
<em>El loro </em>that translates into <em>parrot </em>and is a tropical bird, often brightly colored, with a short down-curved hooked bill, grasping feet, and a raucous voice, found commonly in the tropics and feeding on fruits and seeds. It is often kept as a pet and can be taught to copy what people say.
<h2>4) Right answer</h2><h3>arena</h3><h3 />
<em>Sand </em>translates into <em>la arena </em>and is a pale brown substance that you find at the beach or in the dessert, formed from very small pieces of rock. The word <em>arena </em>is a feminine noun, that's the reason why the definite article that determines this noun is <em>la </em>(feminine and singular definite article)
<h2>5) Right answer</h2><h3>este</h3><h3><em></em></h3>
<em>Este </em>translates into <em>this </em>and just as we said above, this is used to refer to something near to the speaker in space or time. Since I, the speaker who is describing a crab (saying that it is ugly), am near the crab and <em>cangrejo </em>is a masculine and singular noun, I need to use the demonstrative adjective <em>este. </em>
<h2>6) Right answer</h2><h3>estos</h3><h3><em></em></h3>
<em>Estos </em>translates into <em>these </em>and is masculine plural form of <em>este. </em>So, in this sentence fishes are also near the speaker. So I am saying I like these beautiful fishes. The reason why we choose<em> </em><em>estos </em>is because peces is a masculine and plural noun. Therefore, demonstrative adjectives must match the noun they determine in both gender and number.
<h2>7) Right answer</h2><h3>esos</h3><h3><em></em></h3>
<em>Ese</em> indicates something more distant, that is, nouns that are further from the speaker but they can be close to the listener. In this sentence, the noun we are talking about is <em>cerdos, </em>which is masculine and plural. The demonstrative adjective that matches <em>those </em>and is masculine and plural is <em>esos </em>that comes from <em>ese.</em>
<h2>8) Right answer</h2><h3>ese</h3><h3><em></em></h3>
<em>Ese</em> translates into <em>that </em>and must be used here because <em>pez </em>is a masculine and singular noun. So here the fish is further from the speaker but it nos not necessary that it is close to the listener. So suppose you are the speaker and I am the listener, then the fish is further from you but it can be near me.
<h2>9) Right answer</h2><h3>esta</h3><h3><em></em></h3>
Since canasta is a feminine and singular noun, we must use the demonstrative adjective <em>esta. </em>So here the basket is near to the speaker in space. Since we are talking about <em>location, </em>then we are talking about <em>space </em>here. Therefore, my purpose is to buy<em> this</em> old basket.
