Some of the problemswhich I got wrong ________ (must / come) from that...

Explanation:

The correct answer is "must have come". Let's break down the sentence to understand why this is the correct choice.

1. Past tense:
The verb "got" in the sentence indicates that the problems are being referred to in the past tense.

2. Possibility:
The word "must" expresses strong possibility or probability. In this case, it suggests that it is highly likely that the problems originated from that day.

3. Modal verb "have" + past participle:
To express an action that happened before another past action, we use the modal verb "have" followed by the past participle form of the verb. In this case, the past participle of the verb "come" is "come". Therefore, we use "must have come" to indicate that the problems came before the time of reference.

4. Not "must come":
Using "must come" would imply that the problems are currently happening or will happen in the future. However, since the sentence is in the past tense, we need to use the past form "must have come" to correctly convey that the problems occurred in the past.

Example:
To further illustrate the correct usage of "must have come," consider the following sentence: "I found a book on the shelf that must have come from the library." This sentence implies that it is highly likely that the book originated from the library at some point in the past.

Therefore, in the given sentence, "Some of the problems which I got wrong must have come from that day" is the correct answer as it accurately conveys that the problems originated from that day in the past.

Similar Verbal Doubts

By regarding the expanding universe as a motion picture, you can easily imagine running the film backward. If you do so, you find the universe getting smaller and smaller, and eventually you come to the moment when its whole mass is crammed into an infinitely dense point. Before that time it didnt exist, or at least it didnt exist in its present form. Though there is some controversy about its exact age, most cosmologists would be inclined to agree that the universe has existed for about ten to twenty billion years. For scale, this can be compared to the four-and-a-half-billion-year age of the solar system, the time since the disappearance of the dinosaurs (sixty-five million years), and the age of the human race (about three million years). The event that marked the beginning of the universe was christened the Big Bang; the term has now entered the vernacular of our culture. Originally the name referred only to the single initiating event; now, however, astronomers have come to use it to mean the entire developmental process of the birth and expansion of the cosmos. The simple statement that the universe had a beginning in time is by now so obvious to astrophysicists that few give it a second thought. Yet it is a statement that has profound implications. Most civilizations embrace one of two opposite concepts of time. Linear time has a beginning, a duration, and an end; cyclical time, as its name suggests, continues around and around forever. In a universe that functions through cyclical time, the question of creation never arises; the universe always was and always will be. The minute you switch to linear time you immediately confront the vexing question not only of creation, but also of the Creator. Although there is no logical reason for the assumption, many people believe that if something comes into existence, it must do so in response to the actions of some rational being. Because of that belief, astronomers, even though they resist becoming involved in theological discussion, find themselves in one when they posit the Big Bang universe. It puts them squarely in the middle of an age-old debate. One common misconception about the Big Bang that should be disposed of immediately is the notion that the universal expansion is analogous to the explosion of an artillery shell. The galaxies are not like bits of shrapnel speeding away from a central explosion. The raisin-indough analogy is a more satisfactory way to think about the whole process.

Suspicious as they are of American intentions, and bolstered by court rulings that seem to give them license to seek out and publish any and all government secrets, the medias distrust of our government, combined with their limited understanding of the world at large, damages our ability to design and conduct good policy in ways that the media rarely imagine.The leak through which sensitive information flows from the government to the press is detrimental to policy in so far as it almost completely precludes the possibility of serious discussion. The fear that anything they say, even in what is construed as a private forum, may appear in print, makes many people, whether our own government officials or the leaders of foreign countries, unwilling to speak their minds.Must we be content with the restriction of our leaders policy discussions to a handful of people who trust each other, thus limiting the richness and variety of ideas that could be brought forward through a larger group because of the nearly endemic nature of this problem? It is vitally important for the leaders of the United States to know the real state of affairs internationally, and this can occur only if foreign leaders feel free to speak their minds to our diplomats. Until recently, it looked as if the media had convinced the public that journalists were more reliable than the government; however, this may be changing. With the passage of time, the media have lost lustre. Theyhaving grown large and powerfulprovoke the same public skepticism that other large institutions in the society do. A series of media scandals has contributed to this. Many Americans have concluded that the media are no more credible than the government, and public opinion surveys reflect much ambivalence about the press.While leaks are generally defended by media officials on the grounds of the publics right to know, in reality they are part of the Washington political power game, as well as part of the policy process. The leaker may be currying favour with the media, or may be planting information to influence policy. In the first case, he is helping himself by enhancing the prestige of a journalist; in the second, he is using the media as a stage for his preferred policies. In either instance, it closes the circle: the leak begins with a political motive, is advanced by a politicized media, and continues because of politics. Although some of the journalists think they are doing the work, they are more often than not instruments of the process, not prime movers. The media must be held accountable for their activities, just like every other significant institution in our society, and the media must be forced to earn the publics trust.Direction: Read the above Paragraph and answer the follownig QuetionsQ.Based on the passage, when the media now challenge the actions of a public official, the public assumes that
