Question

look at the word endeavor in the passage below.
i cant believe the inventors fair is next week! im still working on my idea.
first, i began to design a bike lock that was both lightweight and unbreakable, but the necessary materials were too expensive. next, i worked on a machine that would brush my cat and feed him treats at the same time. unfortunately, smokey hasnt been willing to test it.
my third endeavor is a device to protect the plants in my dads garden from being nibbled on by wild animals at night. the portable, screened cover includes a motion - sensing light to scare away hungry intruders. after working on it for three days, i think it has real promise. maybe it will win the grand prize!
what is the meaning of endeavor as used in the passage?
a negative event or disaster
a challenging project or plan
an annoying creature or pest

Explanation:

En el contexto del texto, el autor menciona tres proyectos diferentes (diseñar un candado para bicicleta, una máquina para cepillar al gato y darle golosinas, y un dispositivo para proteger las plantas del jardín). El término "endeavor" se utiliza para referirse a estos proyectos. Al ser el tercer intento después de dos anteriores (el diseño del candado y la máquina para el gato), se infiere que se refiere a un proyecto o plan. Además, el autor describe el tercer "endeavor" (el dispositivo para proteger las plantas) con entusiasmo ("has real promise. Maybe it will win the grand prize!"), lo que descarta la idea de que sea algo negativo (como "a negative event or disaster") o molesto (como "an annoying creature or pest").

Answer:

B. a challenging project or plan
