A person can swim at a vigorous pace for 30 minutes without getting tired. what is an appropriate long-term goal for this person? to swim at a vigorous pace for one hour by the end of one week
to swim at a vigorous pace for one hour by the end of two months
to swim at a vigorous pace for 20 minutes by the end of two months
to swim at a vigorous pace for 25 minutes by the end of two months

to swim at a vigorous pace for one hour by the end of two months

Explanation:

'C' and 'D' cant possibly be right cause the goal is to swim for longer not shorter. 'A' can't be right cause you cant possibly learn to swim faster from 30 minutes to an hour in only a week, that just sounds impossible.

im totally guessing here, but i think 'B' is right.

if you think your dog may have been exposed to a toxin, the best thing to do is to check the label of the item you think your pet ingested. read the information about toxicity. often, but not always, the information on packaging regarding children is relevant to dogs and some manufacturers even discuss dog toxicity. if there is an 800 number on the package – call them! it’s also recommended that you call your veterinarian to confirm the recommendations. if you go to your veterinarian, take all packaging and any information you have on the product.
