If you want to see flowers of Tragopogen pratensis in bloom, you will need to look for them before lunch because it lives up to one of its common names Jack-go-to-bed-at-noon. Whatever the weather, flowers of this common member of the dandelion family close by midday. It's one of a number of species whose floral movements can be used as a primitive clock. Scarlet pimpernel opens and closes depending on temperature and humidity change, but finally closes for the day at about 3 pm, rain or shine. The gardening writer JC Londou in 1872, planned floral clocks constructed from species with this kind of behaviour, claiming floral opening and closing times to an accuracy of minutes. Though they have fairly predictable opening and closing times, their time keeping ability would have been constantly disrupted by variable weather. And so it is not surprising _______.
  • a)
    that Londou's clock was popular in the 19th century
  • b)
    that Londou's clock can be seen only in horticulture gardens
  • c)
    that Londou's erratic botonical time piece never caught on
  • d)
    that Londou's clocks are among the most accurate of primitive clocks
  • e)
    that Londou is highly respected by botanists
Correct answer is option 'C'. Can you explain this answer?

If you want to see flowers of Tragopogen pratensis in bloom, you will ...
Let's analyze each option:
(A) That Londou's clock was popular in the 19th century: This option is not supported by the information given. The passage mentions that Londou planned floral clocks in 1872, but it does not provide any information about their popularity or success.
(B) That Londou's clock can be seen only in horticulture gardens: The passage does not provide any information about where Londou's clock can be seen. This option is not supported by the information given.
(C) That Londou's erratic botanical timepiece never caught on: This option aligns with the information given in the passage. The passage mentions that Londou planned floral clocks but their timekeeping ability would have been constantly disrupted by variable weather. This suggests that Londou's clock, despite having predictable opening and closing times, was not successful in practical applications due to the inconsistency caused by weather variations.
(D) That Londou's clocks are among the most accurate of primitive clocks: The passage does not provide any information to support this option. It mentions Londou's clock planning but does not indicate that his clocks were particularly accurate.
(E) That Londou is highly respected by botanists: The passage does not provide any information about Londou's reputation or how he is perceived by botanists. This option is not supported by the information given.
Based on the information provided, the most appropriate option to complete the sentence is (C) That Londou's erratic botanical timepiece never caught on.

Climatic conditions are delicately adjusted to the composition of the Earth’s atmosphere. If there were a change in the atmosphere—for example, in the relative proportions of atmospheric gases—the climate would probably change also. A slight increase in water vapor, for instance, would increase the heat-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the amount of solar energy reaching the Earth’s surface.The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth’s incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3.If, because of an increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2 would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increases and decreases of a set magnitude.Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature increase of at least 1. But a supposed global temperature rise of 1 may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.The author refers toVenusprimarily in order to
