Is it possible for whales to go beyond 60 tons, or beyond the length of 60 feet in real life?

Yes this can might be possible but the weight of whales is not More than 60 tons.  Another condition that's describe in you question me could be consider as well as right.

the most ethic and honorable thing for the newspaper to do are:

be completely transparent in reporting about the company’s attempt to trade favors.

contact other construction companies to tell them about the situation.

these two options are the most ethic because both promote the market fair course, by telling the other competitors about the company attempt to get ahead in the market by trading favors, the market is guaranteed equality and justice in the trading of goods and services.

3 is blunder, i’m not sure about the last one but the first two look correct
