Eight north Indian Ocean countries, namely, Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, were asked to contribute names so that a combined list could be compiled. Each country gave eight names and a combined list of 64 names was prepared. This list is currently in use, and all cyclones arising in the north Indian Ocean are named from this list, with one name from each country being used in turn. Almost 38 or 39 names from the list have been used up, but since many cyclones dissipate long before they hit land, their names rarely figure in the papers or other media. The names that people do know about, and remember are, naturally, those that were most destructive ones, or very recent. Aila, in 2009 is remembered with a shudder for the enormous destruction it caused in West Bengal and Bangladesh; Phaillin, also for the damage it caused when it hit the Odisha coast in 2013. Two harmless cyclones, which also might remain in peoples memory, are the more recent ones of 2014 — Hudhud, which threatened the east coast of India and Nilofar, which was expected to, but did not, devastate the western coast. The names in the cyclone list are usually words one associates with storms; words which mean water or wind or lightning in various national languages. Sometimes they are names of other things — birds or flowers or precious stones. The name Aila, contributed by the Maldives means fire, the name Phaillin from Thailand means sapphire, the name Hudhud from Oman is the name of a bird, probably the hoopoe, and the name Nilofar, given by Pakistan, is the Urdu name of the lotus or water lily. The eight names suggested by India, and which are in the list of 64, are Agni, Akaash, Bijli, Jal, Leher, Megh, Sagar and Vayu, meaning in that order, fire, sky, lightning, water, wave, cloud, sea and wind. Five of these names (that is, up to Leher) have been used so far.
Which of the following names is a type of a precious stone?

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 is 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. According to the passage, which of the following is NOT a desirable parameter for a vaccine?
