The chemicals used on farms, golf courses, and domestic gardens are often to blame when groundwater becomes contaminated with a. acid b. nitrates c. fuel d. sewage

The correct answer is option B i.e. Nitrates.

Explanation:

1. The golf courses, or cricket and football grounds need a thick sheet of grass growing on them for their perfect performance. Farms do need grasses for animals.

2. Acid is not poured on the grasses to grow. Some nitrates poured on grass may convert into nitric acid, but its not significant.

3. Fuel and sewage are also not poured on golf courses or farms to grow grasses.

4. But nitrates are good fertilizers which leads to growth of grasses and plants, needed for farms and golf courses.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
