English is not my first language, and I’m having trouble understanding correct transitions with the word “however.”
On our mock ACT the question was:
Snowflakes form from tiny water droplets, following a specific process of chemical bonding as they freeze which results in a six-sided figure. The rare "triangular" snowflake, similarly, confounded scientists for years because it apparently defied the basic laws of chemistry.
The correct answer was J.
In another example:
I wasn't planning on going to the wedding, however you've convinced me that it's a good idea.
A. NO CHANGE
B. wedding, however,
C. wedding. However,
The correct answer was C.
According to the previous example, why is the answer B incorrect?
