For  many  years,  most  vehicles  in  the  U.S.  were  gas  ,  relying  on  fossil  fuels  for  energy.  These  cars  contributed  to  air  pollution  and  climate  change.  The    to  find  cleaner  alternatives  led  to  new  innovations  in  the  automotive  industry.  Engineers  began  designing    electric  cars  that  were  both  fast  and  stylish.  They  also  developed    cars,  which  use  a  renewable  energy  source  to  reduce  emissions.  These  advancements  are  helping  create  a  more  sustainable  future.

Correct answer: powered

Explanation: You hear "were gas powered". The word comes after "gas", so you need an action word ending in ed.

Meaning: "powered" means given energy to run.

Wrong options:

  • powred: It leaves out the "e". Write "powered". Only the exact spelling gets the mark.
  • power: "power" is missing the ending. The speaker says "powered", with "ed" at the end.
Correct answer: urgency

Explanation: Listen for "The urgency to find". You need a short word for a thing, person or idea that means a strong need now.

Meaning: "urgency" means a strong and quick need to act.

Wrong options:

  • urgancy: It has "a" where the word has "e". Check the letters: "urgency". A small spelling mistake loses the mark.
  • emergency: This is a different word about danger, not the strong need described here.
Correct answer: sleek

Explanation: On the recording you hear "designing sleek electric cars". The word before "electric" is a describing word for style.

Meaning: "sleek" means smooth, modern, and stylish.

Wrong options:

  • sleak: It has "a" where the word has "e". Write "sleek". Only the exact spelling gets the mark.
  • slick: This is a different word with a different idea. The sentence needs 'sleek' for stylish design.
Correct answer: hydrogen

Explanation: Listen again to "developed hydrogen cars". The word names a clean fuel type, so spell the chemical name.

Meaning: "hydrogen" means a fuel made from the lightest gas element.

Wrong options:

  • hidrogen: It has "i" where the word has "y". Check the letters: "hydrogen". A small spelling mistake loses the mark.
