have to rewrite these sentences, correcting the problem of incorrect omission.?

5. Johnny never has and never will study his geometry.
6. Women on the whole understand children better than men.

thank you in advance..

Sra is right. You need to think in terms of which preposition or prepositional phrase is missing in each sentence. You can also think of these as incomplete comparisons.

1. A liberal arts background is excellent for such professions as lawyers and doctors.
Are lawyers and doctors professions?

2. American colleges consistently produce more physical education teachers than biology.
Is biology a teacher?

3. My mother has great admiration and belief in my father.
The correct preposition is there for the second of the two -- "belief in" -- so what preposition should be there after "admiration"?

4. The light at the intersection of Gurley and Montezuma will turn green exactly three seconds after the intersection of Gurley and Marina.
The light turns green after the intersection??

5. Johnny never has and never will study his geometry.
Does the verb "study" go correctly with both "has" and "will"?

6. Women on the whole understand children better than men.
This sentence is unclear. Do women understand children better than men do? Or do women understand children better than they understand men?

I still don't understand..

1. A liberal arts background is excellent for such professions as lawyers and doctors.

To rewrite the sentences, correcting the problem of incorrect omission, follow these steps:

1. Identify the missing words or phrases that need to be added for clarity or grammatical correctness.
