Problem: Under modern constitutional conventions, the sovereign acts on the advice of his or her ministers. Since these ministers most often maintain the support of parliament and are the ones who obtain the passage of bills, it is highly improbable that they would advise the sovereign to withhold assent. An exception is sometimes stated to be if bills are not passed in good faith, though it is difficult to make an interpretation on what this circumstance might constitute. Hence, in modern practice, royal assent is always granted; a refusal to do so would be appropriate only in an emergency requiring the use of the monarch's reserve powers.
Modern-day sovereigns often acts on the advice of whom?
The answer is the following: ministers

Problem: The interactions of carbonate anions with uranium(VI) cause the Pourbaix diagram to change greatly when the medium is changed from water to a carbonate containing solution. While the vast majority of carbonates are insoluble in water (students are often taught that all carbonates other than those of alkali metals are insoluble in water), uranium carbonates are often soluble in water. This is because a U(VI) cation is able to bind two terminal oxides and three or more carbonates to form anionic complexes.
What does a uranium(VI) cation form when it binds to two terminal oxides and three or more carbonates?
The answer is the following: anionic complexes

Problem: With limited resources Muawiyah went about creating allies. Muawiyah married Maysum the daughter of the chief of the Kalb tribe, that was a large Jacobite Christian Arab tribe in Syria. His marriage to Maysum was politically motivated. The Kalb tribe had remained largely neutral when the Muslims first went into Syria. After the plague that killed much of the Muslim Army in Syria, by marrying Maysum, Muawiyah started to use the Jacobite Christians, against the Romans. Muawiya's wife Maysum (Yazid's mother) was also a Jacobite Christian. With limited resources and the Byzantine just over the border, Muawiyah worked in cooperation with the local Christian population. To stop Byzantine harassment from the sea during the Arab-Byzantine Wars, in 649 Muawiyah set up a navy; manned by Monophysitise Christians, Copts and Jacobite Syrian Christians sailors and Muslim troops.
Where was the Kalb tribe based?
The answer is the following: Syria

Problem: Lossy data compression is the converse of lossless data compression. In these schemes, some loss of information is acceptable. Dropping nonessential detail from the data source can save storage space. Lossy data compression schemes are designed by research on how people perceive the data in question. For example, the human eye is more sensitive to subtle variations in luminance than it is to the variations in color. JPEG image compression works in part by rounding off nonessential bits of information. There is a corresponding trade-off between preserving information and reducing size. A number of popular compression formats exploit these perceptual differences, including those used in music files, images, and video.
What can save storage space?
The answer is the following:
Dropping nonessential detail from the data source
