identical twins look the same, but there are some differences in their bodies. patrick flynn, a computer scientist from the university of notre dame in the united states, uses computer technology to look closely at identical twins. computers can recognize people when they cut their hair or grow a beard. so how about twins? can computers tell the difference? the answer is: yes! while computers can tell from people feel computers are good at noticing very small physical differences, but humans can miss things like differences in the size of freckles.
so what can humans do to identify identical twins? their personalities can be different. one twin may be quiet, while the other twin may be talkative. they may also like different things and have different hobbies. looking alike (doesn’t) mean acting alike.

Explanation:

Question 1

The article starts by saying identical twins (chemical twins here) look the same physically. Option a says they look very different (wrong), option c says humans can't tell apart (but the text later says humans can tell some differences, but the first part is about looking the same). So option b matches as the first part of the article shows they look almost the same.

The first paragraph describes two identical twins' physical features (short dark hair, dark eyes, same height, same sweater) to give an example of how chemical twins (identical twins) look alike. Option b is about showing differences (first paragraph shows similarities), option c is about describing the twins in the photo but the purpose is to exemplify their similarity. So option a is correct.

The text says "Computers can recognize things such as differences in the size of freckles" and "Patrick, a computer scientist... uses computer technology to look closely at identical twins. Computers can recognize people who are identical? No. They can tell small differences like differences in the size of freckles." Freckles are a type of blemish or mark, so option a (freckles) is what Patrick's tech can see. Option b (hairstyles) - the twins have same hair? Option c (eye color) - they have dark - colored eyes, same. So a is correct.

Answer:

b. look almost the same
