Are cruise ships built for the transatlantic run?

The Queen Mary 2 was built for transatlantic crossings, but much smaller ships can make the crossing easily. In 1995, I crossed the Atlantic from New York to the Azores on the Royal Princess (which was not the same ship as the current Royal Princess), which was about one fourth the size of the QM2. Just about any seaworthy passenger ship can navigate the Atlantic safely, if not comfortably.

If I was 2 weeks pregnant and rode on a roller coaster do you think my baby would have died?

No. A mother's womb is a highly protective place in spite of all the tv shows and movies that try to depict that a pregnant woman is extremely delicate. Miscarriages that early in the pregnancy are very frequent and more usual than you may think. A roller coaster in the latter part of a pregnancy is another story altogether.

What are the common Pitfalls in construction industry?

From a project management point of view. There exist a tension between the

consultants that the client of a new construction project employs and the builder ( Contractor). The Client employs certain proffessionals such as the Architect ( Principal Agent), Engineers, Q.S etc as consultants to supervise the successful delivery of His new construction project. However The Builder ( Contractor) is also employed via tendering and acceptance of tender, to bring the Clients building plans complete and successful. So in essence all these proffessionals are employed to contribute to the final building product and needs to work hand in hand and in co-operation with each other. For they all have a common goal and purpose and need to work towards it. There tends to be however certain lapse in the unity of this team of proffessional when project completion dates need to be met, and reputations are at stake. And subsequently, consultants want to defend themselves by attacking the builder and the builder defends himself by attacking the consultants. There are a number of reasons for this pitfall, such as lask of information to the builder from consultants or failure of the builder to express timely notice of information needed or clarity on information given to mention but a few. The result of this pitfall is very unfortanute, and is best avoided. The result being the common goal is shifted and indiviuals aiming to please clients needs to cover their backs, rather than the ultimate goal of delivering a successful building project where unity can achieve more than anything else.

That being said, the best interests of the client must never be forgotten by the consultants when dealing with the contractor and the Contractor should remain

committed to the advice and instructions of the consultants who look after the clients interests, for everyone to achieve the common goal and maintain the respect of each party in the Building project.

Will technology one day progress to the point where there will not be a need to distinguish between hardware and software meaning that no difference would be perceived between the 2 types of interface?

No, hardware is of necessity a physical mechanism and software is procedural information. The same software can run on very different hardware, as long as it interprets it the same way producing the same physical effect will have the same result. But hardware without software will do nothing (unless the hardware is fixed single purpose hardware that needs no software).

What should be the essay about the theme of English language enlarges human experiences with greater understanding and compassion to nature?

Perhaps you should discuss some inspiring poetry in the English language which deals with the topic of nature, or any other writing in English that you have found to be particularly eloquent, on that topic.

Answer

Linguistically, English has been a language that readily borrows words from other languages, so there are many choices of words for the same thing, each with a different nuance. For example, for rain: shower, downpour, precipitation, drizzle, rainstorm and, out in Arizona: spit (drops of rain that catch the dust and put it on your windshield).

There are also phrases and sayings that have been made popular after people hear them and find them useful. Check out the common phrases from Shakespeare in the related link.
