"brown" is an adjective that correctly describes the noun "dog."

The other options are incorrect because:

loudly – adverb (describes how the dog barked)

quickly – adverb

runs – verb

Explanation

 "He runs very fast."

"very" is an adverb used to intensify another adverb (like "fast").

"much" and "many" are typically used with quantities (e.g., "much time", "many apples").

"more" is comparative (e.g., "He runs more quickly than her").

Explanation

"He is doing his homework now."

The present continuous tense is formed using:

$$text{am/is/are} + text{verb-ing}$$

Subject "He" takes "is", and the base verb becomes "doing".

Explanation

“By” is used as an adverb of time in the future perfect tense.

"They will have completed" is correct.

It indicates that you will have finished something by a certain point in the future.

Thus, 0! = 1

Explanation

"I like both apples and oranges."

The phrase "both ... and ..." is a correlative conjunction pair used to show the inclusion of two items.
