43. To determine the correct answer, we need to look at the gender and number agreement in the sentence. The adjective "fácil" agrees in gender and number with the noun it modifies, which is "semestre." In this case, "semestre" is singular and masculine, so we need a matching singular, masculine form of the article.

Looking at the options:
a. "el primero" - This is the correct option, as it matches the gender and number of "semestre."

b. "el primer" - This is incorrect because it's the singular, masculine form of the article, but it doesn't match the gender of "semestre."

c. "la primera" - This is incorrect because it's the singular, feminine form of the article, and it doesn't match the gender of "semestre."

d. "la una" - This is incorrect because it's a combination of the feminine article "la" and the feminine number "una," which doesn't match the gender of "semestre."

Therefore, the correct answer is (a) "el primero."

47. To determine the correct answer, we need to identify the subject of the sentence, which is the one doing the action of "enseñar" (to teach) the five classes.

Looking at the options:
a. "El señor Blanco y la señorita Martin" - This option suggests that both Mr. Blanco and Miss Martin teach the five classes, so it could be the correct answer.

b. "Profesor Diaz" - This option suggests that Professor Diaz teaches the five classes.

c. "Señor Jimenez" - This option suggests that Mr. Jimenez teaches the five classes.

d. "La señora Garcia" - This option suggests that Mrs. Garcia teaches the five classes.

From the options, it seems that (a) "El señor Blanco y la señorita Martin" could be the correct answer if they both teach the five classes.

49. To determine the correct answer, we need to identify the correct pronoun that fits in the sentence in relation to "Paco."

Looking at the options:
a. "yo" - This option suggests that Paco and "I" need markers. This does not fit the context of the sentence.

b. "tú" - This option suggests that Paco and "you" need markers. This does not fit the context of the sentence.

c. "Margarita y yo" - This option suggests that Paco and "Margarita and I" need markers. This could be the correct answer if Paco is included in the group.

d. "Vosotros" - This option suggests that Paco and "you all" need markers. This does not fit the context of the sentence.

From the options, it seems that (c) "Margarita y yo" could be the correct answer if Paco is included in the group.

50. To determine the correct answer, we need to identify the correct interrogative word that fits in the question.

Looking at the options:
a. "Dónde" - This option means "where" and is used to ask for a location. This is not the correct answer for the given question.

b. "Quién" - This option means "who" and is used to ask for a person's identity. This is not the correct answer for the given question.

c. "Adónde" - This option means "to where" and is used to ask for a destination. This fits the context of the given question, as it asks about the destination where the person is going.

d. "De dónde" - This option means "from where" and is used to ask for a person's origin. This is not the correct answer for the given question.

Therefore, the correct answer is (c) "Adónde."
