Read the passage and answer the questions that follow. Evaluation of candidate vaccines for COVID-19 should be done on technical parameters and programmatic suitability. An ideal vaccine would provide the following- immunity that is of a high degree (90%+ protective especially against severe illness), broad-scale (against different variants) and durable (at least five years if not lifelong); a vaccine that is safe (little or no side effects and definitely no serious adverse effects); a vaccine that is cheap (similar to current childhood vaccines); a vaccine that is programmatically suitable- single dose, can be kept at room temperature or at worst needs simple refrigeration between 2 degrees Celsius and 4 degrees Celsius, needle-free delivery, and a vaccine that is available in multi-dose vials, has long shelf life and is amenable to rapid production. Obviously, a vaccine having all these desirable characteristics is a pipe dream, and most vaccines fare well in some and not so well in other parameters, making it difficult to choose between them. What is the most appropriate meaning of the phrase PIPE DREAM?

Select the correct answer using the code given below:
In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is. Statement: Should all vaccines be made free? Arguments: I. Yes. There are many deadly diseases and lower classes of society cannot afford getting vaccinated. II. No. Many vaccines are quite costly. Subsidising them is enough.  
Sentences of a paragraph are given below in jumbled order. Arrange the sentences in the correct order to form a meaningful and coherent paragraph. A. Research is ongoing to answer this question. B.
