Hello,

I need some help with the questions below.
Thank You

#1Which sentence is grammatically corret?
( My choice is A)

A.El río más grande del mundo es en sudamerica.

B.Africa no está tan grande como Eurasia.

#2 Which sentence is grammatically correct?
( My choice is A.)

A.Esta cosa es un lapiz amarillo.

B.Esta cosa es una lapiz amarilla.

Thank you for using the Jiskha Homework Help forum. In A. Sudamérica is capitalized and requires an accent mark. B. is correct IF you wish to say "doesn't SEEM" whereas "no es" would be "it isn't."

In #2, A and B both require an accent mark on "lápiz" and with that accent mark, B is correct.

If you don't know how to make accent marks with the computer, we can show you how if we know whether you have a MAC or a PC, with Windows or not.

Hello!

Let's go through the questions and explanations for each option:

#1 Which sentence is grammatically correct?
( My choice is A)
A. El río más grande del mundo es en Sudamérica.
B. África no está tan grande como Eurasia.

Your choice is correct! The grammatically correct sentence is option A. "El río más grande del mundo es en Sudamérica" means "The largest river in the world is in South America." The subject and verb agree in gender and number, and the preposition "en" is used correctly to indicate location.

Option B is incorrect because it uses the adjective "tan" (so), which is not appropriate for comparing sizes. It should use "tan" (as) to compare, as in "África no es tan grande como Eurasia" (Africa is not as big as Eurasia).

#2 Which sentence is grammatically correct?
( My choice is A.)
A. Esta cosa es un lápiz amarillo.
B. Esta cosa es una lápiz amarilla.

Great choice! The grammatically correct sentence is option A. "Esta cosa es un lápiz amarillo" means "This thing is a yellow pencil." The article "un" is used because "lápiz" (pencil) is a masculine noun.

Option B is incorrect because it uses the feminine article "una" with the masculine noun "lápiz." It should be "un lápiz amarillo" instead.

I hope this helps! Let me know if you have any further questions.
