Premises:
Esteria increased oil prices, Maria lives in Esteria
Maria uses electric based public transport and electric based household power, and stays away for oil fuel in here daily life
Conc says - maria isn't affected significantly by the rise in oil prices
we would have to weaken it by showing Oil prices do impact her
Option A - links Maria with Public Transport which runs on oil prices, which is good so far, we could assume that the public transport might have increased ticket prices and there go Maria getting affected, but it adds in an additional statement that the public transports are funded by the gas tax, so doesn't weaken
Option B - similar concept as A, Groceries and essentials that Maria purchases are delivered by oil-fueled trucks, meaning the delivery charges could have risen to keep up with their fuel costs, so it will impact Maria .... so keep it
C - if Employee stays home, so will Maria, it does save some of her money that she spends public transport, but it doesn't talk about how oil is gonna impact her, her life mostly stays the same with minor saving from transport charges
D - this does impact as the electricity prices goes up, so will Maria cost of living rise, but Oil or Fuel price increase impacting her is not stated here, so OOS doesn't weaken
E - lol option, it talks about economist and their concern on the Esteria economy, it doesn't even talk or touch oil-maria link, so eliminate (unless some deep meaning is behind this, which i am failing to see)
So going with B
