Section A: Multiple Choice Questions (5 marks)

  1. C) Warm-blooded
  2. B) Harper Lee
  3. A) Au
  4. C) Mars
  5. B) Mitochondrion

Section B: Short Answer Questions (7 marks)

  1. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen. Its importance in the ecosystem lies in its role as the primary source of energy for most life forms and the production of oxygen necessary for respiration.

  2. Two examples of renewable energy sources are:

    • Solar energy: It is obtained from the sun's radiation and converted into electricity using photovoltaic cells.
    • Wind energy: Generated by harnessing the kinetic energy of moving air using wind turbines.

  3. Supply and demand is an economic principle that describes the relationship between the quantity of a commodity that producers wish to sell at various prices and the quantity that consumers wish to buy. When the demand for a product increases while its supply remains constant, the price typically goes up. Conversely, if the supply increases and demand remains unchanged, the price tends to decrease. For example, during a drought, the supply of crops may decrease, leading to an increase in prices.

Section C: Three-Mark Question (3 marks)

  1. Impact of climate change on biodiversity:
    • Habitat loss: Changing climate patterns lead to altered habitats, affecting species that rely on specific conditions.
    • Species extinction: Shifts in temperature can outpace species' abilities to adapt, leading to increased extinction rates.
    • Ecosystem disruption: Climate change affects ecosystems' delicate balance, impacting interdependent species and their relationships.

You are not splitting the text into two, since your text does not contain the string "answer key:". There is a string "Answer Key"...is that where you want to divide the text?
That's why you get the error that the list has only one element (you are trying to access to the second element, which doesn't exist), because you are not really splitting the text. You must use a separator string included into the text (for example "Answer Key"). Remember that the split block is case sensitive.

Should I use other string to split?

@Ramon is right here.
You may replace answer key: with Answer Key, so the split method should be working as expected.
