Identify the incorrect sentence.
a. i have been working on this math problem all night.
b. the miners have been digging for weeks.
c. the movie been running for three hours.
d. the two countries have been fighting for more than fifty years.

Sentence "c" is incorrect.

Explanation:

The sentence "the movie been running for three hours" is ungrammatical because the verb "been" which is in the past participle form plus the verb "running" which is in the progressive form indicates that an action that started in the past is still in progress. The name of this tense is present perfect progressive and It is formed with the auxiliary have + been + V-ING. That's why the sentence "the movie been running for three hours" is wrong because the verb requires the auxiliary "have" to form the present perfect progressive. So the correct version would be: "the movie has been running for three hours."

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
