Is this supposed to be a question?
Answer:
The cultural lag describes what actually takes place in the social system when the ideals that governs the society are not able to keep pace with the advances that are most of the time, but not actually always the technological advances. There norms are life support, stem cell research and findings, and cancer vaccines when we deal with American society, which is quite the fastest to keep pace with the technological advancement in general. Its possible now technologically to keep a person alive than he normally lives, but society still needs to accept this. The others are similar, and hence the other two norms. United States is a developed civilization, however still the life after death has not been accepted, however, extended life is definitely a possibility now. Its is quite expected however that soon it is going to be accepted. Hence, its a matter of time only, but since it has been not accepted till now it is a cultural lag. Stem cell research is also a similar situation. But soon it will be accepted as well. Hence, US can be supposed to be the most advanced society, and the above cultural lags are for the time being only, and soon will be accepted. None of the other countries, you can expect these to be accepted currently. That is why US is the most advanced society of the world. However, some ethical conflicts and crisis still exist, but it will be removed soon, which is expected.
Explanation:
The answer is self explanatory.
Answer: c. You have little risk of having your credit card number intercepted.
====================================
Explanation:
Choice A is false because it is an advantage to be able to choose goods from any vendor from anywhere in the world. The more competition, the better the outcome for the consumer.
Choice B can also be ruled out since that's also an advantage for the consumer. You don't have to worry about shop closure and that kind of time pressure is non-existent with online shops.
Choice D is also a non-answer because shopping online is faster than shopping in a brick-and-mortar store.
The only thing left is choice C. There is a risk a person's credit card could be intercepted or stolen. This usually would occur if the online shop isn't using a secure method of transmitting the credit card info, or their servers are insecure when they store the data. If strong encryption is applied, then this risk can be significantly reduced if not eliminated entirely.
Answer:
Replace the comment with:
(c) double hours = Math.abs (marker1 - marker2) / 60.0;
Explanation:
See attachment for right presentation of question
Analyzing the options:
(a): May return a negative result
This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.
This literally is not different from marker1 - marker2
(b): Incorrect expression
This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.
(c) This option is correct
This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)
(d) & (e) Integer division
When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
