Reading the passage
What does each account actually say about barite? A calls it a very heavy mineral and mentions its food and medical uses. B also identifies it as a heavy mineral. That shared characteristic gives us a straightforward prediction.
Working the answers
- A
A says nothing about barite's dispersal in seawater. B's dispersal comparison concerns the mud mixtures, not a separately stated property of barite in both accounts.
- B
A includes clays and barite among mud ingredients. Neither account gives this exclusion from bentonite-containing muds.
- C
A doesn't discuss tight regulation of barite's use. B's regulation of discharges doesn't make this a characteristic stated in both.
- D
Largest ingredient by weight, as A describes barite, isn't the same as most commonly used ingredient. B doesn't supply that frequency claim either.
- ECorrect
A calls barite “a very heavy mineral”; B calls it “a powdered heavy mineral.” Both explicitly identify its heaviness.
