determine word meanings using known words and suffixes -ment and -able — instruction — level c
complete the sentences.
“you did a great job completing another successful project!” said dr. moss to her class. “you’ve built a real, computer for our lab. you of your achievement .”
options: improvement, usable

Explanation:

To solve this, we analyze the context and word parts:

1. The sentence is about a successful project and a computer built for the lab, focusing on a positive result of their work.
2. "Improvement" (with the suffix -ment, meaning an action or result of improving) fits here as it refers to the positive change/result of their efforts (building the computer, completing the project). "Usable" (with -able, meaning capable of being used) doesn't fit the context of a result of their achievement.

For the first blank (the one with the dropdown, assuming it's the first blank before "computer"):
The context is about a positive change or result from their work. "Improvement" (noun, from "improve" + -ment) makes sense as "improvement computer" would be a computer that's an improvement (though the sentence structure might have a typo, but from the dropdown, "improvement" is the correct choice for the context of achievement and project success).

For the second blank (already filled as "achievement", which is correct: "achievement" is from "achieve" + -ment, referring to their successful work).

If we assume the dropdown is for the first blank (before "computer"):

• "Improvement" (with -ment) refers to a positive change/result, fitting the context of a successful project and lab computer. "Usable" (with -able) refers to capability of use, not matching the "achievement" - related result context.

Answer:

For the dropdown blank: improvement
