Cosmo is a scientist. He is conducting an experiment to determine if microscopic yeast particles are living organisms. He divides a Petri dish into four sections and spreads a sample of yeast into each section. His Petri dish is pictured below.

Cosmo knows that yeast reacts chemically with sugar. So he adds different amounts of sugar to each section of his Petri dish. He is careful to keep each section separated from the others. In one of the sections, Cosmo does not add any sugar at all.

He waits one week and then carefully observes each sample of yeast under a microscope. He makes several observations. These observations are listed below.
Each sample of yeast remained separate from the other three samples.

The three samples that were given sugar showed evidence of a chemical reaction.

The sample that was given the greatest amount of sugar reacted with the sugar the most.

The yeast that received no sugar responded by forming and releasing spores.
Which observation provides the best evidence that Cosmo's yeast particles are living organisms?
A.
Observation #4
B.
Observation #1
C.
Observation #3
D.
Observation #2

the vast majority of ballots have been counted nearly two weeks after one of the biggest political upsets in modern u.s. history catapulted donald trump to the presidency.

estimates show more than 58 percent of eligible voters went to the polls during the 2016 election, nearly breaking even with the turnout rate set during the last presidential election in 2012, even as the final tallies in states like california continue to be calculated, according to statistics collected by the u.s. elections project.

but among those figures were stark contrasts in key states that swing the election to trump — in ohio, wisconsin, iowa, michigan and elsewhere — indicating the president-elect’s leap from long-shot candidate to the most powerful political position in the world may have happened in part because of apathy toward hillary clinton’s candidacy, especially among the democratic base, several political scientists and organizations monitoring voter turnout told the pbs newshour.

while clinton is leading the popular vote by more than 1.5 million over trump as of sunday, she trails president obama’s 2012 totals by more than 2 million ballots — a chasm that may have cost her the election, said david becker, co-founder of the center for election and innovation and research.

“several million voters didn’t come out to vote,” becker said. “which is telling me that this idea of the trump wave, a huge number of voters shifting over to trump, is certainly not the story.”
