Question 1:
The five sentences labelled (1, 2, 3, 4, 5) given in this question, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the proper order for the sentences and key in this sequence of five numbers as your answer.
1. Scientists have for the first time managed to edit genes in a human embryo to repair a genetic mutation, fueling hopes that such procedures may one day be available outside laboratory conditions.
2. The cardiac disease causes sudden death in otherwise healthy young athletes and affects about one in 500 people overall.
3. Correcting the mutation in the gene would not only ensure that the child is healthy but also prevents transmission of the mutation to future generations.
4. It is caused by a mutation in a particular gene and a child will suffer from the condition even if it inherits only one copy of the mutated gene.
5. In results announced in Nature this week, scientists fixed a mutation that thickens the heart muscle, a condition called hypertrophic cardiomyopathy.

The five sentences you provided, when properly sequenced to form a coherent paragraph, can be arranged in the following order:
1. Scientists have for the first time managed to edit genes in a human embryo to repair a genetic mutation, fueling hopes that such procedures may one day be available outside laboratory conditions.
2. The cardiac disease caused sudden death in otherwise healthy young adults and affects about one in 500 people overall.
3. Correcting the mutation in the gene would not only ensure that the child is healthy but also prevents transmission of the mutation to future generations.
4. If a mutation in a particular gene and a child will suffer from the condition even if it inherits only one copy of the mutated gene.
5. In results announced in the journal Nature, scientists fixed a mutation that thickens the heart muscle, a condition called hypertrophic cardiomyopathy.
So, the correct order for these sentences should be: 1, 2, 3, 4, 5.
This sequence is logical because it starts with the announcement about editing genes for a specific mutation, introduces the context of cardiac disease, explains the importance of correcting the gene, talks about the inheritance implications, and concludes with the specific results from the research【4:16†source】.
