Answer : 4. "Both B and C"
Explanation :
The underlined part of the sentence is grammatically incorrect. The preposition 'for’ used here is wrong. The correct preposition should be 'to’.
Gauge means to judge or assess (a situation, mood, etc.).
Hence 'assess’ is a synonym of 'gauge’.
Both choices B and C are correct. Hence the correct answer is option 4.

Answer : 2. "Some inherited genetic mutations can be good for the offspring."
Explanation :
Answer: B) Some inherited genetic mutations can be good for the offspring. Explanation: Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit. Genetic mutations that cause diseases are not always passed on to offspring.
