Make the following plural:
un lápiz
o un lápices
o unos lápices
o unos lapizes
ounas lápices

The correct option is the second one: unos lápices

Explanation:

In spanish when a noun finishes with -l, -r, -n, -d, -z,  or-j, the plural will be constructed with -es termination.

For example:

1. Singular: animal (animal) Plural: animales (animals)

2. Singular: mar (sea) Plural: mares (seas)

3: Singular: reloj (clock) Plural: relojes (clocks)

4: Singular: lápiz (pencil) Plural: lápices (pencils)

In addition, spanish has the adjective's flexion, which always corresponds to the number of the noun, thus the termination -os in unos indicates and reaffirms the plural of the noun.

the author develops a cold, and scared tone. making the reader shudder with fear, and suddenly become cold. i'm guessing that he's writing a scary novel, or maybe about a chilly december night.
